I can help, but your not going to like it . . . You will need to
perform a hard reset . . .
This will return your treo to its factory install, and delete everything you have installed to this point. You might not be out of the woods however. If something is corrupt in your install, when you sync back, it might happen again. If it does, you can remove those items from the desktop, but we will worry about that one once you get your device reset . . . .
