First off, Color Jack is a cool little tool, and fun to manipulate. It’s for anyone who’s ever wondered, “what colors would look good with this?”
Now, when I try it in Firefox is works fine. Just slide the points around and they do their thing. In Internet Explorer, the program runs with an agonizing slowness. You’d think that color sphere was comprised of 10,000 bump-mapped self-shadowing polygons. It gets about a frame a second. How can it possibly be that slow?
