MASSIVE KLUDGE: It turns out that the DOS debugger ends up
calling MouInit & MouDeInit every time a screen swap occurs
(no matter what the flipping mechanism is). Doing the mouse
driver initialization every time is extremely slow. Things seem
to work if we only do the driver initialization the first time
through. Talk to Brian Stecher/John Dahms if you run into problems
with not doing the initialization all the time.
