Ah, true.
Revised improved patch attached (untested except for OS X). The X11  
and OS X ports behave the same: as soon as a window receives a mouse- 
enters event, the mouse window is set to this window. When a mouse- 
leaves event is received the mouse window is set to NULL. The windows  
code is unchanged from the previous patch; I can't figure out how to  
do this in the same way for Windows, but it may not matter since on  
Windows top window = key window = mouse window.
What this patch fails to do is keep the value of mouse window if a  
button is held down while the mouse leaves the window (so the mouse  
window is set to NULL at that point). This shouldn't be hard to fix,  
but it requires some book keeping.

Yup, quite useful, thanks :)
