I guess I've been using CursorXP for so long and I have (had) so many cursors downloaded that I didn't want to switch.
PLUS, I really didn't know that FX was susposed to be an 'upgrade' to xp. I actually thought it was the other way. I too am running Vista and xp works fine - except I cant seem to find the cursors anymore.
One thing I did notice, is Trails. I can't have trailers when I tried fx.
