I just installed tc2.3 yesterday and havn't thoroughly tested it.
See these things can be reproduced.
1. If I open Xfe file manager (sometimes as sudo) and click on /mnt, it shows all of the drives and partitions. It also shows a directory called test. Should that be there?
2. You can mount a partition in Xfe by right clicking and selecting Mount. When using flwm this does not work. It works OK with jwm.
