beats me.  I don't think that VR mode deactivates the buffer when the frame 
is not in focus, so it's always seemed redundant to me.  There may be some 
issue with the way that VR mode tracks changes to the buffer, using an 
overlay.  This is probably not the best way to do it, there are other ways 
of having Emacs report changes (before- and after-change-functions), that 
Barry was not aware of when he designed VR mode.  Several people have 
suggested to me this is a better way of doing it, and it certainly much 
simpler than having to manage the "VR-overlay".  I want to make this 
change, but it's kind of a big one and I'm not sure it's worth the effort.

2. Is there a regression test suite for VR mode?

surely you are joking!  :-)

No, there are no such tests.  Most of the time it's readily apparent when 
something breaks, VR mode is a fragile piece of software that seems to be 
living on the edge all the time... :-)

If you want to play with VR.el, would you like to become a developer on the 
SourceForge project?  That way, you can just make a branch in the CVS and 
it would be easier to keep track of what's going on.  Let me know, and I'll 
set it up.
