Hi,

I've a problem with the XamWebDialogWindow (version 10.1, latest release).I've a popup that shows up every 10 seconds (wusing a storyboard timer). The problem happens when my main application window is minimized.

I get this exception :

"Message : Unhandled Error in Silverlight Application
Code: 4004   
Category: ManagedRuntimeError      
Message: System.ArgumentException: La valeur n'est pas comprise dans la plage attendue. (which means "Value does not fall within expected range")
   à MS.Internal.XcpImports.MethodEx(IntPtr ptr, String name, CValue[] cvData)
   à MS.Internal.XcpImports.MethodPack(IntPtr objectPtr, String methodName, Object[] rawData)

   à Infragistics.Silverlight.Controls.XamWebDialogWindow.CenterDialogWindow()
   à Infragistics.Silverlight.Controls.XamWebDialogWindow.XamWebDialogWindow_LayoutUpdated(Object sender, EventArgs e)
   à System.Windows.FrameworkElement.OnLayoutUpdated(Object sender, EventArgs e)
   à MS.Internal.JoltHelper.RaiseEvent(IntPtr target, UInt32 eventId, IntPtr coreEventArgs, UInt32 eventArgsTypeIndex)"    

If this is a bug , is there a way i can avoid it through a little workaround or something ?

Thanx.

EDIT :  I also set the popup StartupPosition Property to "Center" and restrictInContainer to "true"
