I'm getting this 'mprexe' error 'This program has perfomed an illegal
operation...', can anyone point me in the right direction?? It's
locking up the computer (Windows 98, Compaq Armada E500/6650, I just
defragged the hard drive, the error comes up right after the Novell
client flashes). The computer has been running very slow, now it
won't run at all. Any help is appreciated. Thanks! Ann, AMFAB
