This takes a while. I still don't think this thing is working. That's not really a question, but I'll answer the question that it implies. Different browsers deal with k-5 in different ways. IE5 seems to handle k-5 better than any browser.
Load times are usually less than one minute.
NN4.x doesn't do quite so well, but eventually does load k-5. Times are closer to 2.5 minutes. In addition, NN4.x updates the elements one at a time, so you get to watch the 50 states be drawn in alphabetical order. NN6 seems to mangle this program a bit. However, it is still completely functional.
