In addition to the sensitivity problem, there is another annoying problem which I hope may be fixed in 12.10. It used to be that with the auto-hide on, with no program covering the launcher space, the launchers would be visible. ONLY when some program covered up this space to gain additional real estate, would they actually disappear. In particular, when no program was running, they would be visible.
I had hoped this would be fixed in 12.04 but so far it continues to be broken. Has anyone seen if it is maybe fixed in 12.10?
