I also have noticed that it seems each application uses it's own settings, rather than the attempt at a global one I created.
*This* drove me crazy. After poking around for a while a while back I did find an option for something like "reset settings to default". Had to first set up the options I wanted in the main MUI Prefs program, then load each offending app and fix them. I think I found it by right-clicking on the page headings, will try to scratch it up again and give better instructions if you can't find it.
Also a changelog between 3.8 & 3.9 would be nice! :hammer:
