    Here's my scenario.  My Visual Studio 2010 Web Application has just been upgraded from an older version of Telerik to the newest version (Q1 2012 SP1) to support IE9.  I am noticing quite a few UI issues and some things that stopped working.  The most prominent is the resizing of controls on the screen.  We used to use the AjaxManager's "OnResponseEnd" to fire a "resize" client-side function and all was right with the world.  That apparently has stopped working and I was wondering if the newest version of the ASP .NET controls need some extra work.

    I have a MasterPage within my "MainPage.aspx" file which holds my main menu.  Under the main menu I have a UserControl (which is really just an iFrame).  Depending on which menu item is selected I load a specific ASPX page into my iFrame user control.  Now my "MainPage" has a RadAajaxManager on it and the ClientEvents get called correctly (OnResponseEnd is what I'm using) with no issues. 

    My UserControl (simple ASCX file) does NOT have a RadAjaxManager ... but the ASPX page it loads DOES have one.  For example:
    userControl.FrameSource = SubPage.aspx;

    SubPage.aspx DOES have a RadAjaxManager ... but I cannot get the OnRequestStart or OnResponseEnd to fire.  Like I mentioned before...this was all working in the old version of Telerik on IE7 and 8 (comp mode).  Is it my code, new Telerik, IE9?  Any help would be greatly apprecited.

    Thanks all,
