The question marks on your files is Supermount playing up.
You have two options:
1) Logout - Login.
2) Reboot if logout/in didn't sort it out.
Supermount is the only bugbear I have with Mandy. Konsole doesn't seem to be able to sort it either - get the 'device busy' blah blah.
You can sort it out by perma unmounting your CD-Rom. You can do this from the MCC under Mount Points. It just means you have to Konsole/mount every time you put in a cd and konsole unmount when you're done.
OK, you sorted it whilst I was typing
I think I'm going to write a tutorial so I don't have to keep typing all this out. heh.
