Your right, the picture window does use JavaScript (document.writeln) to spit out the HTML.
It's one of those weird problems.
Have you noticed that there is a minor JavaScript Error on every page on the site? I have errors turned on on IE and it says:
Line 103
Char 1
Error: Object expected.
That's typically a JavaScript error. It looks like it's around the same plkace as the code to show the banner ad and popup. I think you should remove them
I know why you need them, just joking.
