Has anyone else noticed the bug in MouseInit(), which is supplied as part
of MOUSE.C ?

The bare _asm{ ret } when the mouse is not available is NOT the way to
return( 0 ); without trashing the program stack.

If the code is changed to split the _asm block and use a return() instead,
then it works fine. I guess everyone at Microsoft has a mouse ?
