Comment 4 for bug 381155

It does happen when just moving the mouse, no window in tow.
I followed the "Applications -> Settings -> window Manager; Advanced tab and uncheck "Wrap workspaces when pointer reaches the screen edge". The box was unchecked. I checked the box, and restarted X, the problem still occurred, I unchecked the box, and restarted X again. Upon login, the problem is still occurring - in short the box makes no difference, though unchecking "Wrap workspaces when dragging a window off the screen" will prevent a workspace changing if I'm dragging a window.
