hi mathgogocart

Thanks for posting those. The first two looked very good to me. Loads to try.

But I couldn't get the third to stay loaded. IE9 kept rejecting the site. I've tried to go to it via google but, same problem. Odd. That's the second time in a week that I've had problems with a site. I shall investigate further.

It would be intertesting to know how it loads for others.

There is nothing with the 3rd link on my computer. I am using GC.

By the way, Bob, I really suggest you change your browser. Only old people use those!
