Thank you for the quick answer. I thought that may be the case. Without going through all the possible scenarios can you tell me if it this is possible to overcome by placing the content within a iframe inside the dialog and setting the source of the iframe via javascript before the dialog loads. i.e. something like this:
<a href="javascript:showme()">Show Dialog</a>
<script>
function showme() {
dlg = eo_GetObject('Dialog1');
document.getElementById("myiframe").src = "jcara.aspx?userid=139395"
dlg.setCaption("<table width=100% bgcolor=blue cellspacing=0 cellpadding=0><tr><td align=center><font color=white>Gallery for - " + username + "</font></td><tr><table>")
dlg.show(true);
}
When the above example was tried it no longer made me click the back button three times but it still made me do it twice before it went back to the previous page. So I was no longer using the content URL but it still seems to affect the browser history for some reason.
As far as the other other issue I got that one solved it was nothing more than a stupid typo LOL.
