At the prompting of AT&T, I switched from DM 4.3 to DM 4.6. First synch went OK. Now (day 2), I plugged in to synch again, and DM4.6 immediately opened box with message: "Checking for device application updates. Please wait..."
I have left the 8700c connected for 15+ minutes with no change. When I unplug the BB, the DM4.6 screen stays up, along with the message box.
I can't seem to find a setting to change. Any advice about this? I would like to synch again, but can't get beyond the initial screen.
