Have you tried restoreSCR.reg yet?
How do other screensavers run? - Are they jerky also? - Or is this version of MA the
ONLY one that's jerky?
When you uninstalled it, did you run Morgan's regclean script, before reinstalling? (It cleans out the registry).
Have we established which version of MA it is? - Does the same happen with MA2, MA2MD, MATime, Time2MD?
ps, - Good one Clint!
