windows- ghosts or not ?

ok i had a costomer bring in his computer the other day,with a problem I havent seen before,as
I am farely new to my job. Anyways he informed me that every once in a while his computer would start cascading through his start menu all by itself (not actually running anything)but just flashing through the start menu. I asked the seasoned tech about it and actually showed it to him when it did it on my bench. But he didnt know either. I have checked everything,ran test,virus,hardware,software,and everything seems to be in order. But I have no clue?
So is his computer really haunted or is it just gremlins?????
It is a P11 450 mghrz nothing special
no heat problems and he has 64mb of mem 40 gig hd
anybody have any Ideas cause I have rulled out all mine ...
thanks In advance kosslo

I was thinking/guessing it might be sticking keys or something gone amiss with the debounce circuitry. For those who don't know what debounce circuitry is... when you press a key on a keyboard the key actually bounces on the switch that it closes (somewhat like dropping a ping pong ball) causing it to open and close several times. The debounce circuitry filters the output from the switch so only one keystroke is sent to the computer. I did not think of a keyboard with an integrated mouse, which is a likely possibility as well. Whenever one has a computer problem, one should ask, “what changed?” Larry
