    Ok- Here's one for you. I too had severe digitizer problems- had to recalibrate every 20-30 minutes in use. Bought my TT last year and the problem appeared a couple of months ago and has gotten worse. It seemed to get worse when I opened and closed the slider. I installed the patch- no effect or it made it worse. Then thought it was a software issue. I did a hard reset, did not install the patch or any 3rd party software except ZLauncher. The problem reappeared. So I did what any real man would do- I took the TT totally apart!
    I discovered that some of the internal contacts were slightly tarnished (oxidized?) I cleaned them with an ink eraser. I also unplugged the internal battery from the TT while I was working on the TT. Lastly, I discovered a small (approx 3x4 mm) black pad that was stuck on the back and inside of the slider. It's use to me was unknown, so I did what any real man would do- I left it out!
    I reassembled my TT. The problem is totally gone!! My slider seems to open and close a lot easier. I don't know if the black pad is used for friction or what. I installed most of my previous apps and still no problem! I gave my TT a workout- open and closed the slider, opened and closed various apps- still no problem.

    This brings me to several questions as to what the problem was.

    A) The internal contacts were oxidized and this caused the digitizer problem. This would seem to make sense, since the problem developed over time.

    B) By unplugging the internal battery, the TT lost all power and
    some unknown program/virus was lost. Ok, I'm reaching for that one!

    C)The mysterious black pad was the culprit. This could make sense, since opening and closing the slider seemed to make the digitizer worse.

    I have not installed the latest TT update. I want the sound patch but not sure if I want the digitizer patch.

    I would appreciate any feedback on this one.

    Ericrph - very interesting findings. I give you credit for having the nerve to take your Palm apart. I seriously doubt the virus theory and the oxidation is questionable too. However, I can not argue with your results. I am glad to see that you Palm is running more reliably after your surgery.

    I have been running with minimal 3rd party app for 2 days and have not had to recalibrate once. So I am leaning towards the "bad 3rd party software" theory. I moved a lot of SW over from my Palm IIIc to my TT.

    I tried opening and closing the slider to see if I could force the screen out of calibration, but no luck there.

    I wish there was a definitive solution to this problem. It certainly is helpful to discuss the issue in this forum. Collectively we should be able to come to a reasonable conclusion.

    regards,
    Scott

    Ericrph, were there any stickers that said if they were removed the warranty would be voided?

    I'm having the same problem but it seems to coincide with installing the new TT updater. I haven't tried uninstalling the updater but i am about to. Has anyone been able to ruled out any 3rd party apps that could be causing the problem?

    OK well that's how it is with *your* Palm. I think I described pretty clearly why I believed that on *my* IIIxe the drift problem was caused by errant software. Your mileage may vary, so take it easy with the "cop out" accusations. I was simply relating *my own* experience.

    It is certainly not impossible that someone else might have the same experience I did. I made my comments in good faith and I resent any other implication.

    I assume that when you say that hard reset improved the situation for a few days, you're talking about not reinstalling any applications for those few days?

    As far as why other brands of PDAs don't have digitizer drift problems, try using any search engine and search on the terms "digitizer pda brand" where pda brand is any other model of PDA. If you find a model that doesn't return any results, report back. I've seen reports of Handsprings, Treos, Clios, every kind of Palm, Newtons, iPaqs... and I haven't even tried hard.

    I have no doubt that there can be either software or hardware causes for digitizer problems. Sorry I couldn't have been of more help, but I really only have my own experiences to go by.

    I've been having the digitizer drift problem for the past few days, out of the blue, and I have NOT installed the new update from Palm. I did install the two seperate patches (audio and digitizer) a few months ago.
    I don't think it's related to the new patch, and I don't think anyone has isolated an offending application yet.... :(

    I did a folder compare of my currently installed apps and the apps that were installed when I was having calibration problems.

    Eliminating all the data files and applications that others would not have I am left with the following list of suspects which could be causing the recalibration problem. I have been running without these apps for 3 days and have not needed to recalibrate.

    amped.PRC
    AvantGo.PRC
    Bejeweled!.PRC
    FineTypeManager.PRC
    Graffiti_Anywhere.PRC
    Graffiti_ShortCuts_.PRC
    Keyboard_Hack_II.PRC
    Launcher_X.PRC
    LXBrowser.PRC
    MobileDB.PRC
    MobileLink.PRC
    MoHiSp1Lib.PRC
    MoHiSp1Lib_.PRC
    MoreFont.PRC
    PalmPatch.PRC
    PN_Cache_Library.PRC
    PN_Display_Library.PRC
    PocketLink.PRC
    ProxiWeb_Comm_Library.PRC
    ScptPlugin.PRC
    Sonic_Hedgehog_h.PRC


    ps: I used the following app to compare the folders http://www.simtel.net/pub/pd/59383.html

    I have installed all of my previous apps including the big TT update file. I am pleased to report that my digitizer problem has completely disappeared!

    Did you reinstall the applications or just copy the to install from a backup folder? Do you believe it was a hardware problem ?

    This is a curse. I've never had a digitizer problem before. I read this thread yesterday and was counting my blessings that I hadn't incurred the problem. Well, that was a curse, because today it showed up. It seems like it only affects the right hand side of my screen, e.g. can't use the slider. I've recalibrated already 3 times today! Such a pain, such a pain.

    Welcome to the recalibration club. My problems have always been localized the the right side of the screen. It makes using the slider or opening an attached note impossible until a recalibration is done.

    I have been running fine for 4 days with most, but not all, of my 3rd party app reinstalled. Take a look at an earlier post to see what I have not put back.

    That's it. Precisely! If you open a notepad and draw around the screen, you'll see how the "ink" drifts away from the stylus tip as you get further to the right.
    I wish someone would come up with the definitive offending application... I have a feeling it is not strictly a hardware problem, but rather has something to do with an app. But that's just a hunch.

    I did a fresh install of all apps. I even deleted the palm desktop software and reinstalled it. I sync with MS Outlook so I was able to retain my contact and schedule information. I truly believe this is not a software issue, since I installed all of the same apps, albeit some were newer versions. I also mentioned I had digitizer problems after a hard reset and just installing Zlauncher.

    Swieder, I'm curious, why do you not think the problem is with the internal contacts? I don't know much about electronics but the tarnished contacts did raise some suspicions. I once saw some pictures posted of the insides of a TT on the web, but I can't find it now. I would show you where the tarnished contacts were. Did you know the internal speaker is conected to the board by 2 small springs? Interesting.

    Also, is it not possible to have some kind of TSR-like program on the TT that you can't get rid of except to disconnect the power source?

    My partner at work bought a TT after I did and he just mentioned he is now starting to have digitizer problems. Perhaps he would let me take apart his as well.

    I'm convinced that in my case it's software. I am a rehabilitated Picture Logic addict. Every time I played Picture Logic my digitizer required recalibration, until I gave up a removed it. Occasionally I reload it and after a few hours I have to remove it again.

    I even tried installing Digifix, but I still had problems until I gave up on my favorite game.

    I too have only been noticing the problem over the past couple of days. The only new software I have loaded are VersaMail2.5 and the palm patch

    I am also having this problem with "digitizer drift" and it seems to have developed over the past four weeks. It's very interesting to see the number of people who are having this problem recently. It almost sounds much more like a software issue than hardware (what's the chance of everyone's hardware starting to screw up at the same time?).

    I wonder if a software upgrade (or virus????) has caused this?

    Can we start comparing what software each of us has installed? If we can find some common applications then we can do some testing to see if that is the culprit.

    Look at my earlier post to see what I do not have installed. Since these programs have been left off I have not had to recalibrate. It has been 5 days.

    Actually quite good, if they were manufactured around the same time.

    Within a few hours of installing Grafitti Anywhere 1.3.1 (GA) my TT went out of Calibration for the first time in 5 days.

    Given the nature of GA it could be the offending application that is causing this widespread problem. I deleted GA for now, did a hard reset and restore and will continue to monitor my progress.

    I also got a SRO number for Palm to repair/replace the Hardware. They are telling me that it could be 7 days to turn the unit around. I thought that I had advanced replacement with my "premium policy" from Radio Shack. I do not. I am thinking about buying the Palm extended warranty which provides for Adv replacement and an extra year of service. Any thoughts about this option?
