 	Sorry, that's my fault.  I tried it both ways.

 	Ok, that explains it then.  I'm on 2.2.4.

 	Have we considered the possibility of mapping things using an xkb-like 
set of config files?  Or even integrating it into xkb?  I note that we have:
-	Something that maps virtual buttons to physical buttons
-	Something that maps a physical axis (scroll wheel) to a virtual set of
 	buttons
-	Things that invert and swap axes

 	I don't see any reason why these couldn't be done in an xkb-like 
fashion, although in the second and third cases, these might need to be 
implemented in the driver instead of via xmodmap (assuming I understand 
xmodmap correctly).

 	Am I correct in understanding that, in this diagram:

 	...the xmodmap program also affects the dark green box (possibly at 
the point where the word "compiles" appears)?

 	Thanks,
