title: Suppressing touch points in Silverlight WP7
body: <p>I'm writing a hybrid XNA + Silverlight app for WP7 and I'm trying to work out the touch splitting between them. I've got this halfway worked out: I can suppress XNA <code>TouchPanel</code> touches when the user clicks a Silverlight button. However I have not figured out how to throw out game-only touches for Silverlight. So if you're holding a touch point in the game space (say, for moving the player around), a second touch on a button won't work. It think it's picking it up as a multi-touch gesture and only allowing the first touch point to click buttons.</p>
  
  <p>My question is: how can you suppress this touch point in Silverlight processing?</p>
