Try Mouse function INT 33, function 08 - Set Vertical
range, to *expand* the size of mouse area. Normally, it
defaults to a virtual screen of 640 by 200 points (Which
don't have to correspond to pixels - depending on what you
are doing....) Also, Function 7 is used for the
Horizontal range...
-Hope this helps
