I think Dale has nailed the "lost files" problem accurately. The Vista User Control Access (UAC) bit MUST be turned off or Vista can play havoc with your files, moving them, deleting them, hiding them, and other nasties. We had one user in FL who lost 110,000 song files in under 1 second. If you select 1,000 songs and delete them it will take minutes. Only Windows (Vista) restructuring its index of folders/files could effect that type of damage so fast.
MimiLee, why are you still running version 4.11?
Visit
http://www.mtu.com/upgrades/hoster.htm#411 and scroll upwards to see the versions released AFTER 4.11. You will see there are some very important bug fixes.
In 5.01, we finally discovered a Windows flaw that was causing random crashing when the Playlist contents were used to update the Singers Names Display (SND) on the Show Display. This could appear to be entirely random, which made it so difficult to track down. We found and fixed this, so 5.01 users are reporting no more crashes... VERY STABLE!
