    Hi.

    I'm trying to display a UserControl in a RadWindow. But a few seconds after rendering on screen the browser throws the following exception:
    Sys.InvalidOperationException: ManagedRuntimeError error #4004 in control 'Xaml1' : System.Exception : Catastrophic Failure.

    I am downloading and loading the UserControl at Runtime.

    Hey Gary,

    There was just another post regarding using a ComboBox inside of a dialog,

    http://www.telerik.com/community/forums/silverlight/window/combobox-inside-dialog.aspx,

    and it sounds like this could be related to your problem.  What are the contents of the user control that you are using, any chance one of them is a combobox? :D

    They referenced a service pack later today (woohoo!), so hopefully that has some workaround for the bug Microsoft introduced here.
