I'm running Debian 5.0.7 + GNOME 2.22.2, and since some days I'm having a strange problem.
If I want to move the icon of a file from one point to another of the desktop, a simple dragging will cause the creation of a copy of it. The combination shift+dragging of the file will effectively move the icon as it was happening with simple dragging before the appearance of this strange behavior. This works only with data files and links to folders and is not affecting "Computer" and mounted volumes icons.
Does someone has a clue of what is happened
