Dock won't hide after launching an app from Launchpad
I've searched but haven't seen any other people reporting this. I have my Dock in Lion set to auto-hide, but very frequently when I launch an app it then gets stuck and won't auto-hide. The Launchpad screen disappears as normal but the Dock stays open. I have to hover over it and then move the mouse away to refresh it and it then hides as it should.
Anyone else having this problem? I think I've experienced it since I first installed Lion.
