Sorry, I'm a Mac guy. My last windows machine ran Win98, and
I purged most of that data from my brain long ago!
People have helped resolved OS-based issues on this board
before, but if nobody else here steps up to help, try a microsoft
forum. It sounds more like a Windows issue than a Flash issue.
Here's one. I don't
know if it's the best one, I just googled for it.
Good luck!
