+ I checked out the new version of mouse.c; explicit test to see if fgbits was zero
+ before dividing by it, was what I'd tried--the application runs, but exists; i.e.,
+ this hides the real problem, namely that fbbits shouldn't be zero.  
+ 
+ I also reinstalled the HEAD to try out the other parts of the patch.  I get the
+ same behavior.
+ 
+ As far as I can tell, there was no extra debugging message from the application.
