Instead of polling mouse in a loop, isn't it better to arrange
for the mouse driver to call you when any button is pressed?
There is a function in the Int 33h interface which allows you
to register your function (wrapped in a real-mode callback, of
course) to be called when any one of a set of mouse events you
specify happens.  I did this in DJGPP: worked wonderfully.
