I have to admit that I am a bit of an OS nut. I love trying out new ones to see what they bring to the table. I have used OS X before, but never on a dedicated machine that is mine to use (or abuse as the case may be). In an effort to get the true Mac experience I have borrowed an iMac from a neighbor that is away on an extended business trip. This is a pretty simple question but here is goes anyhow. How in the world do you get the OS to recognize extra mouse buttons? I have a Logitech mouse plugged in and the system has no problem using it for normal functions. However, if I use any of the side buttons (which in Windows default to Forward / Back) they stick me in scrolling mode. A quick Google search brings up some commercial applications, but I am thinking there has to be a free solution isn't there?
