Thanks Doc, I think I knew that
But I don't use the mouse much so I'm unlikely to spot a badly sized cover serendipitously. When my mouse is in that vicinity (rarely) its usually about to open, save, or delete a format
When it's not being used (i.e most of the time) my mouse is told to go and sit quietly on the bottom edge of the desktop - no random walks allowed
