Binary package hint: unity

On all 3 systems where I have installed Ubuntu Natty I've seen this bug. At seemingly random points in time, the Unity launcher will stop autohiding, obscuring both maximized applications and "windowed" applications that sit under the launcher. I'm typically running Emacs and Opera, so perhaps this combination is relevant.

Today I've discovered that toggling the Num Lock state on the keyboard makes the launcher hide. This seems to make no sense, but it is what I observe.

Found no likely duplicates that were still open. unity package is at 3.8.12-0ubuntu1
