On my PC at work I use Autocad a lot and have my buttons remapped to suit my cad needs. Yesterday the HD died and I needed to reinstall the machine. I also had to reinstall crappy intellipoint to map my buttons again and after some fumbling around return to work. I had accidently mapped a mouse button to something called "Instant Viewer" in intellipoint, and low and behold its some sort of primitive expose'. Has this been always been around?
