Can't assign keybinding Ctrl-Alt-w
In 12.04, I am unable to assign the keyboard shortcut Ctrl-Alt-w to anything.
For example, if I go to System Settings - Keyboard - Shortcuts and try to modify the keybinding for "Launch Web Browser" to Ctrl-Alt-w, the window just returns to the main System Settings screen and the new keybinding is not assigned.
I was able to do so without any issues in 11.10.
Can you help with this problem?
