I just realized something and I thought I would share it with all of you. I've been using my Intellimouse Optical for some time now and my only real complaint was that many games don't recognize the left and right buttons (4 and 5). I always knew you could change the functions of the buttons in Windows with the Intellipoint software, but while messing around with it the other day I just discovered that you can set up button profiles for any program that you run. In other words if you want to assign an action like Reload to button 4 in Return to Castle Wolfenstein, all you have to do is use Intellipoint to make button 4 act like the 'R' keystroke whenever that game is running. Pretty neat, huh.
I'm sure some of you already knew this, but I thought it was a neat trick and I just wanted to share it. B)
