The condition may have begun over a week ago; I'm not sure. The small
hourglass figure alongside the mouse pointer easily goes unnoticed but if
it's showing when I try to quit, the computer always hangs up. I don't know
what turns it on. I have eliminated all except Explorer and System Tray but
the hourglass still remains. If, at that point, I restart the computer the
hourglass disappears and I can then shut down normally. Its presence seems
to have no effect at all on other things I do until I try to quit. Please,
where do I look now?
