From the sounds of it, it's Win2K. My day job is in IT support and we're still testing Win2K on some machines....finding all sorts of odd bugs/problems with software/hardware used in our company when installed on a Win2K machine. The problems with Win2K could run from driver support to software compatibility...and then some! If the problem went away with going back to Win98, I agree with you, problem solved. I dread the day when my boss tells me we're gonna switch to Win2K.
