The bug corrupts programs, causing them to abort on startup with the NT error message, "is not a valid Windows NT application." At present, problems have been reported with Microsoft Paint (MSPAINT.EXE),
Calculator (CALC.EXE), CD-Player (CDPLAYER.EXE), but other programs may be susceptible.

Rick - ouch!!!!!!
I've been fighting my way through my first NT install the past week, and everytime I get the OS and SP5 loaded, and then go to load the Toshiba specific drivers I get this message on the next reboot!!

(bitch-wine-moan)

and I thought it was me!!! Thanks for the heads up, looks like I need load anti-virus stuff before my toshiba drivers maybe....
