I haven't yet tried to reproduce this, but sadly it won't suprise me. Some 
older versions of kupu+Firefox2+Windows also used to crash when toggling 
fullscreen mode.

I think the problem is connected with the way that focus works 
asynchronously in Windows: if you step through the code with a debugger it 
will work fine, and if you remove the focus setting code it also works (but 
annoys people because the edit window loses focus on unzooming), and 
changing the order of the lines of code can also stop the crash.

Can you make sure and file a bug in the Plone tracker: I'm hoping to find 
the time to blitz some of the current bugs in the very near future.
