I'm currently running Chromium 18.0.1025.168 (Developer Build 134367 Linux) on Ubuntu 12.04 with dual screens if I change to full screen I can't change back. If I drag the mouse to the top of the screen and left click I see small drop down. (See Figure 1)
When I click F11 the screen attempts to return to normal but then reverts with the same drop down message.
Any ideas would be appreciated.
Extra Information:
The issue doesn't affect the other screen running a parallel instance of Chromium
