Sorry for the repeated and cross post. I wasn't sure which one is causing this issue, UltraWebTab or the WebDialogWindow.
Here is the link to actual post.
Any help is appreciated.
Thanks

These controls cannot be used together. It is a limitation of the old controls - UWT uses WARP internally - and the new controls rely on the ScriptManager and the UpdatePanel functionality.
Please use the WebTab control instead of UltraWebTab
