I have a logitech 3-button mouse, and I have come to rely on the third button as a double-click in OS 9. Not being able to use the third button is one of my major annoyances in OS X (and part of the reason I still use 9 90% of the time). Anyway, I am wondering if there are an hacks out there to use this third button and assign a funtion to it. BTW, this is a serial mouse, not sure if that makes a difference. Thanks.
