Here is one that so far has our IT stumped. Before they take the computer out of the office (rendering the user, well, useless), I wanted to throw this out to the community here.
One of the machines has a message that keeps popping up (see screen shot below). Clicking any of the three buttons or the close window button in the upper right corner does nothing - the window remains. If he reboots, it is still there.
I ran Task Manager and was able to force quite the application once. But after rebooting, this trick did not work a second time
I looked on the interwebs and did not see anything (other than a couple of other peeps asking about the same thing with no answer).
The computer is running Windows 7 Professional.
Any ideas?
ETA: found this link and gonna try tomorrow:
