Ever since I upgraded the OS to PPC 2003 on my X5, it periodically disconnects from Activesync. If I have it in the cradle and connected to my PC, it will disconnect itself for no reason. There seems to be no relationship in what other apps I'm running or time of the day or number of disconnects. Sometimes it will stay connected for hours and sometimes it will disconnect within minutes of docking it. Rom version of the X5 is A05 and I'm running ver. 3.71 of Activesync. The cradle connects to the USB port of a Dell C-Port docking station with a C610 laptop.
Disconnecting started after upgrading to PPC 2003. Before it stayed connected indefinately!

I'm stumped, any suggestions???
