seems to be DM 3.6.3.10, having issues with Handheld software 3.7.1.41. on the 6710.
I just took on a customer who has the same BB as myself. His DM and handheld software were old, so after upgrading his PC, I installed the latest of each. Lo and behold... the same problems as I have been having. DM crashes when synching. So... I removed the the updated handheld software from his system, and it syncs fine now. although now he is still running the older handheld software.
I must say... it bothers me that blackberry software is having issues with its own company software. Anyone have any thoughts on this? I really dont want to remove the 3.7.1.41 from my device. I knda like it alot. But my BB still crashes on syncing!!! ARGHHHH!!!!
