I just got a surprise when I released by Silverlight 4 app to the Win2008R2 server and the ChildWindow.Show calls seem to do nothing. On my Win8 dev machine I see the usual mock modal dialog effect, but on the server there is no visible clue that anything happens. In all other respectes the app seems to be working correctly on the server.
The app seems to be packed into the xap correctly with all the required DLLs. I'm stumped by the bad behaviour and web searches aren't helping. Anyone got a clue? Cheers, Greg K
