Thanks sling-shot but I don't have another usb to hand and, as I have another possibly related problem, I think I may have to do a reinstall of Minime.
This, which I was going to open in another thread, but may as well mention here concerns the file managers.
In the Places panel on the left I used to see Home, Network, Root, Trash, Minime, Windows, Backups, Empty.
Now all I see are the root folders. This makes Konqueror and Dolphin useless and means I can't even save my FF and TB config files.
I don't mind reinstalling from time to time - it gives me a nice new OS without these annoying and time consuming problems.
