I have encountered a strange programming problem.  I redifined the graphics
mouse cursor in my program as follows:

mov ax,9
mov bx,7
mov cx,7
mov es,SEG pattern
mov dx,OFFSET pattern

Those two 7's should put the "hot spot" of the graphics cursor in the center,
seven pixels over and seven pixels down.  Works fine on every Microsoft
compatible mouse I've tried (Logitech, Genius, et al) except one: a real
Microsoft mouse.  Does anyone have any idea why this code works on all
the compatibles but not the real thing?

Thanks in advance,
Eric Ruck
