There are plenty of other problems, including flickering scrollbars in the frame after switching back from fullscreen mode (until the frame is deleted+recreated, or possibly minimized).  And of course it breaks backward compatibility with earlier OS X versions.  

So, code quality is one reason why I have not committed my change here and why I am not ready to assign the rights to the code.  Help with debugging would be appreciated.
