Firefox not displaying popup correctly

Hi All!

I'm using a script to show a popup.
http://www.openwebware.com/products/openpopups/

This displays fine in IE but it does not work right in Firefox. In Firefox
it displays the table but that's it. If I move the call to createWindow
outside of a form tag then I get a small window with a title bar but no
body.
Now if I change the DOCTYPE to HTML instead of XHTML then it display
correctly but the entire page isn't right. Text is too large and bold.

In addition I'm displaying this by clicking an ImageButton. I'm calling it
in the OnClientClick something like this:
onclick="createWindow(.....);return false;"
yet I still get a post back unless I use the HTML instead of the XHTML.

Is there something else that could be done to get this to work right? IE
doesn't like the HTML otherwise I would just use that.

Thanks,
Joe
