Hello, I have these problem. I have a modal dialog, it was with bgiframe=true, and it was working. Then I put the tag : <script type="text/javascript" src="../jquery-ui-1.7.1.custom/js/ jquery.bgiframe.min.js"></script>
and it stopped working. I thought it was that , but I've removed the tag and it still doesn't work. It opens the dialog but instead of the mask , appears a "false" (the string) and no mask. Another issue that I have, is with a z-order of one combobox, that when the masked worked, the combo appeard over the mask. That's why I maked the bgiframe change, but then it didn't worked anymore I hope someone knows how to make it work again.
