I just had a (l)user call me about their computer behaving oddly. Everytime he
tried to open powerpoint it would close the file dialog instantly. He restarted
his machine twice, and he said the novell login box was 'blinking'; it kept
disappearing and then coming back only for a second.

Perplexed, I told him I would have to come see it. I hung up, and he promptly
called back to say nevermind.

Turns out he was holding the escape key down. :-|
