It should be noted that certain applications have dead areas, over which a scroll event will cause the desktop to flip even though the application has the focus. An example is the last.fm suggestions area at the bottom of the Banshee music player. Whether this is a bug in banshee, mono, or gtk+, I don't know. But I do know that it's one way users are introduced to this unexpected "feature".
