Sorry, but I can't find a chat on that page, only a forum.

Simon: Looks like the chat is buried a little deeper in the site:

Marcia, I doubt that this is the chat the reporter talks about. It doesn't use
any flash. I have no problems with the chat you're mentioning and I wasn't
expecting any problems there, because a similar forum system is used on
mozillazine and problems there would be reported very quickly.

Sorry guys, but you have to login first, use my test account: 
user: gerwin 
pass: test, 
than you'll see welcome gerwin, click, and then yo'll see on top a menu with 
chat in it, click on that and voila. And i forgot to tell you that it works in 
ie6 perfect, so it must be posible in mozilla.

Login with Bugzilla/Bugzilla, gerwin/test isn't working anymore

This is no bug. You'll have to call 

test.document.open("text/html", "replace");    // Open the document for writing 
test.document.write('<img.....>');             // Write your HTML 
test.document.close();                         // Close the document.

You could also use:
document.getElementsByTagName("body").item(0).innerHTML="<img...>";

Marking invalid based on that.

Sorry, I misunderstood the problem. But I have done a little more investigating
and found the cause. The buf is still invalid, but the reason is different tahn
the one I've mentioned.

The document you use javascript to open the document in the iframe, the problem
is that once you do that the document no longer has a root (right click->this
frame->frame info, the url is about:blank).

The only way to include the image is by putting in the full url or possibly by
including a base href in the document you've written using document.write.

An alternative would be to use the other method by appending the information at
the bottom of the body element instead of using document.write to edit the contents.

The way to go around this is to open a normal HTML page in the iframe and using 
document.getElementsByTagName("body").item(0).innerHtml += stringToTdd; to
append text at the bottom of the page.
