I've just installed Ubuntu 11.04 and have come across a strange bug, where after using Ubuntu for a while, the launcher suddenly appears and will not hide. This occurs when my mouse is no where near the launcher. I have a duel screen display.
This is very annoying as the launcher appears above the windows I am working on as shown in the screenshot:
I have tried changing the launcher hide options in ccsm but it doesn't seem to make any difference. At the moment it is set to autohide.
Has anyone else come across this?
