I think the problem people are having is CXP has to be uninstalled (save your themes first) before CFX is installed. I have CFX Plus running on 3 machines (Vista Ultimate,Vista Home Prem and XP Pro)and it runs flawlessly on all three. I dl a theme no matter if it's a .curxptheme or a .cursorfx file and click on the file I get a window that says:
Theme copied into theme common folder:
C:\Users\Public\Documents\Stardock\CursorFX\Themes
Do you want to make the selected theme the current theme?

Above is quote from another post with my reply below. I hope this answers some of reply #2 & #5 problems.

Doesn't help with my problem #2 above. I have uninstalled CursorXP, cleaned the registry, reinstalled FX, etc, etc. The program still crashes when a lot of cursors are installed, and it is painfully slow loading. Much worse/slower than CursorXP. Support seems aware of the issue, but there doesn't appear to be a solution yet - except to not use more than 50 cursors. Which isn't much of a solution with so many talented people creating great looking cursors.
