The VNC patch extends the existing mouse handler by passing it abs coordinates as well, (this is the basis of what I used) so there are no additional routines.. I figure if you pass both relative (faked if need be) and abs to the routine then the mouse can use whatever it likes.

That was a kludge. I always meant to do some cleanup there as soon as I got Summagraphics to work with win98 (which has not yet happened :-( ).

Ok, well I'll look at the work that Anthony has put in already and see what we 
come up with.

Speaking of Win98. I just tried this under win98, and after it installed its usb kit and the HID driver it kinda works.. looks like win98 expects 0x0-0xffff while 2k expects 0x0-0x7fff for the position information.. buttons are ok and tracking is good, just the target pointer only moves half the distance.

A problem perhaps, but one that could be worked around in a pinch..
