The power button on the Tx has always been problematic at best. You have to press it just right to get it to work. I have habitually used that button on all of my palms to power on and off. I am now in the habit of using one of the hard buttons, typically favorites. I have the other buttons set to open my most useful apps. Unfortunately, you must use the power button to power off and it is not working well. I just downloaded the following apps to test to power off: Off_Info Off OffitPalm OffStroke I really want to find an alternative before my power button actually dies. I could exchange my Tx, but it is so very stable that I am unwilling to do that. Anyone out there using any of these want to share their experiences? Anyone out there using a different app that they really like. I will definitely report back on my experiences and would love to hear yours.
