I apologize, perhaps I should have been more clear about this initially.

I have to operate this as a dual-use machine.

Was your suggestion that I erase all my Windows applications and files and start over? There are programs that I use that only run on Windows, and I haven't the time to experiment around with Wine to see if they work.

This was my motivation for using Knoppix at all. If I was going to erase the entire HD and start over, I would have chosen another distribution.
