Window control buttons are hard to hit
The close, minimise, and restore buttons are too hard to hit on maximised appplications.
* Open Firefox
* Ensure the window is maximised
* Move the mouse to the very top of the screen
* Note that the buttons don't highlight
* Move the mouse down three pixels
* See the buttons highlight
The clickable area of the buttons should go to the top of the screen.
Seen on natty beta1 with a Radeon graphics on x86_64 Thinkpad R500.
