|Moving Windows users home directories is a pain in the arse. Lots of applications seem to have put related paths in the registry, meaning even if you manage to move the directory it still causes trouble. The only application which broke completely as a result of the move, however, even after the appropriate registry-mangling, was Firefox. Reinstalling it didn't fix it either. Deleting its contents from the user-directory was the only thing that did, meaning annoying reconfiguring and such. Tsk to non-relative data locations.
