I think it has more to do with creating courses with the APCD (millions of clicks), by my mouse is no longer reliable.
I've had two mice that have really served me well. They were both mice that come standard with HP computers, definitely not premium mice, but perfect for me and Links.
I've plugged in a new, costlier HP mouse, but I'm not really betting on it. To me, the proper mouse and the speed of its connection is one of two primary keys to playing Links well... the other is eliminating CPU cycles on processes other than Links.
