title: wp7 - is it possible to have a user control loaded between pages?
body: <p>I'm trying to solve some problems with AdMob control in my game, and the control takes some time to load (it hijacks UI thread for up to 1 second). Is it possible to load the control once, then store it somewhere and attach it to the visual tree for the subsequent pages?</p>
  
  <p>Or this cannot be done and I do have to find some other way?</p>
