Dell XPS 15 (9550) and Silverlight

I just bought a new XPS 15 and I believe I'm having a video driver issue with an application that runs in Silverlight.  The main application works fine but whenever I click an option that is supposed to create a window, the window never appears and it locks up the app.  The only way to get it back is to refresh the page.  I know the app works because on other computers it works fine.  I've tried firefox and the same behavior is present. 

Now my question is, is there a way to force my laptop to use a specific video card?  I have an intel and Nvidia card in the laptop.  All drivers are up to date.
