I am running Windows 7 Enterprise 64bit on a Dell Precision M6700 laptop. Most of the time, I am docked and use two external monitors in addition to the laptop display. However, when I undock and am only using the laptop display, the following happens: If I use the mouse to move a window around at all, when I let go of it, all of my running applications disappear. The windows are no longer visible, the icons on the task bar are no longer highlighted, and they do not exist as running applications in task manager. They still exist as processes in task manager, though. I can kill them from there, but if I do not, they all come back upon redocking. This happens when I move any window except task manager.
Any help?? I have tried and failed to find a similar problem anywhere else.
