I just got rid of the Windows partition on my Mac in anticipation for Windows 7 (a buddy of mine at school got 3 installs of Windows 7 Professional through the interactive media program, and he's giving me one of the installs), so I can't do anything with it now (I don't know how to do it on a Mac, sadly).
But as soon as he gets back to Chicago, I'll get W7 installed and give the fix a try.
Sadly, I don't have access to a 5.1 setup here - I'll have to wait until I go back home (next weekend) to try it out for real.
