UI hang on Mac OS X
After using F11 to get full-screen mode, all operations appear to be inactive. The mouse pointer still works, and F11 will still toggle full-screen, but everything else seems frozen. It is absolutely consistent. I have seen this behavior in both 1.6.7 and 1.6.8.
BTW, I did search to see if this had been reported before and didn't find anything. If I missed a previous report, I apologize.
