Win2k critical update roll-up problem?

After pushing out the new critical update roll-up package to all users, I’m suddenly getting reports of PCs freezing up when the user tries to save a file to a floppy disk. In testing, I’m finding that some systems do freeze and others don’t. Is anyone out there having problems with the roll-up package, or do I need to look elsewhere for a cause?

Thanks,
