I know easy cd 5 caused big problems in w2k. I'm running version 4.0something (whatever the latest patch is, 4.05?) on win2k. My computer has been crashing frequently, and it seems to be tied to this program. cd creator itself dies sometimes (just stops burning in the middle of the disc and won't exit) and often my computer just blue screens. The blue screens don't happen WHILE I'm making a cd, they're usually a while later. Cd creator though is the only thing that seems to be a common thread bewteen when it crashes and when it doesnt. Anyone know what may be going on? For now, I uninstalled cd creator and am trying nero. Hopefully that will stop the crashes...
