I still seem to be finding bugs here, although now I know what to do.
1. The original problem reappears from time to time and I have to reenter the "switch user command". (Maybe after an update?)
2. Secondly, when it does work and I switch to superuser, I get a "Permission denied" message in its own window, however, if I click on OK this window disappears and the folders appear. Maybe this is because many of the folders in my home directory are in fact symbolic links?
