That's cool to have those downloads available. Do you run XP on your computer or are you using Vista? I've had XP for about 5 years and really like it since it is what I learned on.

I'm running Win Vista 64 bit (Super tuned!)... I've learn from other site how to peel the extras off a computer so its like a race car... No style or flash but pure horsepower computer style!

I like that plan.
