I've been on again, off again, on again, off again (mostly off again with life keep getting in the way) for the past 10 years. Believe it or not I had the program Left click, but just had the Right click select drilled into me (by I believe Jonathan Williamson) that I just had to switch it back.
I do hope this old dog can start learning new tricks or I spent $1500 on a glorified paperweight because I don't game.
