Hi,I'll explain you what happened:

Erroneously,when using Nautilus with root privileges..i dragged my "Desktop" folder in the trashcan. I saw that it wasn't in the normal trash(the one in the right bottom),I found it in /root/trash,and I restored it.t

The problem is that now,if I try to drag'n'drop any file i.e. from the right to the left of my desktop, the system don't moves it,but creates a copy of the file! O_O

any suggestions??

Thanks in advance,and sorry for my horrible english!
