I have the launcher set to auto-hide. However, it occasionally stops auto-hiding. So all the windows stay underneath the launcher, but the launcher doesn't hide even when I move my mouse away. I've tried turning auto hide on and off again. While that does change the behavior when it turn auto-hide off (maximized windows don't stretch underneath the launcher), after turning it on again, I have the same problem.
Restarting my computer has always fixed the problem every time I've experienced this issue. This seems to have happened only in the last two weeks or so, and I performed a fresh install of Precise a few weeks after it was released.

This seems odd, does running unity --reset avoid such re-occurrences ?
