I found the problem. The startup HD was locked. I don't know how this happened. I did comm-i and opened the lock, set all to read and write and closed the lock again. All is well now. Strange how this could happen. I didn't noticed the little pencil with a dash trough it in the left bottom corner in the HD window. How bizarre. Paul Moortgat On 05 Feb 2010, at 14:45, T.L.
