Peter,
As far as I can tell, FX 9.1 works fine in the Vista OS.
My graphic card does not support Open GL, but I will fix that and I then expect that it will work across the board.
I have always enjoyed FX because it covers all my needs in my productions.
I will look for the upgrade for the registration issue.
Thanks.
