Here is a work around - You can deactivate the back button. Here is the code to add to the HTML page... It works in Html Dialogs.
<script type="text/javascript">
//for old browsers
window.location.hash = "no-back-button";
window.location.hash = "Again-No-back-button";
"Again-No-back-button";
window.onhashchange = function() {
window.location.hash = "no-back-button";
}
}
//for browsers that support HTML5
history.pushState(null, null, 'no-back-button');
window.addEventListener('popstate', function(event) {
history.pushState(null, null, 'no-back-button');
});
</script>
