I ran into trouble with an installation -- and uninstall left fragments lying around. A re-install didn't work, presumably because of the stuff. I'm now doing the manual uninstall according to the web-page describing this. But there are files in the languages subfolder ending with a .QM extension that I can't delete, even in safe mode (this is on a Windows XP 32bit, SP3). What is locking these 10 files, since deleting these is the only item I couldn't complete on the manual uninstall.
