6.0.6, upgraded from 5.7.8, which was upgraded from previous versions--an existing installation.
Previously installed to default c:\program files\visual cron location, installed new version to e:\program files\visual cron. Settings, Folders were still pointed to c: location. Copied all files to e: location, pointed folder settings to e: locations in VC, applied. Exit out, go back in, all folders remained in original location c:.
Uninstalled via built-in installer and Add/Remove Progs, installed from scratch, still pointing to c: for folder settings.
This seems to go hand in hand w/ my previous post about the "log to event log" not saving. This happens on other servers as well, not just the one.
