There seems to be some bug that has to do with Iron window states. The only time my bottom extension bar behaves normally is when I dock the window using Windows 7's split screen feature. I am running Iron 126.96.36.199 on Windows 7 x64. Screenshots are self explanatory.

Window is docked to left/right half the screen (Windows 7 WinKey+ Left/Right Arrow)http://screencast.com/t/YzY5ZjBkOW
Any help is greatly appreciated.
