Periodically (at least once every few days lately), the Desktop display "bleeds" through the current program I'm running. (See picture) The machine is not hung. I can still launch other applications by clicking a task bar shortcut, but the Desktop itself doesn't respond to anything. The only thing that returns the desktop to the proper display is a restart the computer. This just started happening a couple of months ago. When it first occurred, I immediately ran virus scan on my hard drive, which was 'clean'.
Configuration and usage:
- Lenovo T61P laptop; Windows XP OS
- docking station at home; once a week I un-dock the laptop through the menus and bring it to work
- Usually don't shut down the computer. Instead, I close the cover and it automatically "sleeps".
Can anyone tell me why this is happening (does it have to do with my usage habits above) and/or how I can fix it?
I attached a picture of the problem. If you can't see it well, it can also be seen at this URL:
Thanks for any help you can provide!
