If I close a window in netbook appearence (with Strg + Q) the panel (in autohide option) often hangs (stays) in the next window and make it unusable, until I click the mousebutton (or alt +tab). Reproducible: Sometimes Steps to Reproduce: 1. On different computer the same issue 2. Also on updated (actual) systems 3. Samsung N130 autohide
I don't know if this is the same problem, but whenever I open or close a program the panel gets un-hidden, as might be expected since a change occurs. However, I then have to mouse over the panel to make it hide again.
In my case this only occured in netbook-mode. So I changed to desktop-mode and this behavior was gone.
