Great!  *testing*  it works! :)

Oh - it's a command sequence that's sent to the mouse; the mouse then
switches modes.  The only way to switch back is to reset the mouse
(standard mouseman reset works :)

I'll work on it as soon as I get my #$%! garbage-collection code
working...  multithreaded code is a -pain-...

incidentally, GII works -beautifully- in multiple threads; as does GGI as
far as I can tell :)
[fbcon/2 or 3 different threads writing strings simultaneously:]
.. designing a -very- multithreaded lisp engine... if all goes well, I'll
post it... but it's kinda primitive (no lisp interpreter yet - memory work
is cudgelled by hand.  The console's a bit buggy and GC is -not- working
properly yet due to locking probs...  a lisp interpreter (scheme for now) 
will go in as soon as GC works.  I've -got- a working scheme interpreter
on the sidelines waiting for this :)

BTW - anyone have a working GGI Descent? :)

G'day, eh? :)
