1) mouse is slower: The parameters to 'MouseSetSpeed' are interpreted 
   differently in the two libs: GRX uses the speed value to DIVIDE 
   the mickey count change to get the movement in pixels. 

2) Standard text height/look is a bit different: If you are not
   using the loadable fonts than the only explanation I have is
   that libgr may use the 16 row VGA BIOS font while libgrx uses
   the 14 row EGA BIOS font -- or vice versa??

3) You need to use GRX's own include files (grx.h and mousex.h).
   The bits in the mouse status word have been changed to better
   reflect the MS mouse driver conventions.


Hope this helps:
