XP "Display Properties", "Screeen Saver" tab won't keep selection. Defaults to &
 

I'm running on XP Pro with SP2, Nvidia GEForce4 graphics and the screen saver works fine using "Preview", but then when I apply my settings, close the Display Properties, then re-open Display Properties-Screen Saver, it shows "None" for the selected screen saver. I don't have this problem with other screen savers I have loaded on my system. Tried several times.

In summary, my screen saver setting for MA2 refuses to "stick". I've uninstalled, reinstalled several times with the same result.

If there are spaces in the filename, try taking them out. This worked for me a while ago when I had the same problem.

Yes, you'll need to rename, for instance:
C:\WINDOWS\System32\Marine Aquarium Time 2.scr
to
C:\WINDOWS\System32\MarineAquariumTime2.scr

Yep, that fixed it. Thanks!
