If i try to drag a Folder or a File from a Window to another one, i got the

File Manager Information:
/d2/CDROM/hotmix18 does not exist

(in shell with cp its ok)
Also,when i RightClick on a File and select REMOVE the errormessage appears
(with different Filename of course) again. So,its not possible to
move,rename or copy any
File or Directory (except with Shell).

Any Hint whats wrong on my "new" Octane (6.5.21f) ?
