I've had the same kind of problem on the same kind of computer (Compaq) at different times. Done the virus scan (Norton) and have a firewall to shield myself from incoming. Do regular weekly full scans to help assure no sneaky virus.

Not even aware of any software changes.

I just thought my computer was getting old or was trying to be sympathic to my getting old.

(I was just ignoring the problem but if you get your's solved, Lixy, PM me because I'd like the problem to quit. Hmmmm. Do you think our 'puters' were fooling around and maybe they're going to have a modem or sumptin? )
