   Besides this fact that this is illegal (you didn't Allocate the pot
bits nor did you use gameport.device) please don't use releases like
this, I'll explain why. Intuition allows keyboard shortcuts for the
mouse buttons (Alt-LAmiga=LMB Alt-RAmiga=RMB). Those great C= mice
break down a lot, particularly the mouse buttons. My LMB is slightly
broken and sometimes I have to use the keyboard shortcut. You're routine
kills my chances of using the keyboard or using any non-standard input
device/hack. Use the OS for stuff like this. There a few solutions to this
problem. 1) Install an input handler/commodity and watch RMB events.
2) Use RMBTRAP and then disable RMBTRAP, and fake a mouse  event on
intuition? Would this work?
3) SetMPort on input.device?

  There has to be an OS solution that is better than going to the
hardware.
