That problem has been fixed. If you go back to the download page you were asked to bookmark, you will see that update 4 is up. Each version smoothes out more issues. Right now it is working pretty nicely on my Nexus One. I think there are still some default calendar issues with HTC phones that use the PC Sync calendar, which I don't have. You might want to use it in parallel with whatever your default it (that's what I'm doing). CESD is making improvements rapidly.
