Stuck on first frame on WP8

I'm building a WP8 app as a learning exercise for learning Unity.

This is my problem...

My app seems stuck on the first frame. To start things off I'm simply moving an object from one position to another. The final position is determined by touch. This did not work and it turns out the app is standing on frame one.

Now this all works fine when playing the scene from the Unity IDE and also works fine when building a standalone exe for x86 windows pc. I'm getting no errors on build and nor do I get any at runtime. I build the apps in Unity then deploy them using vs2012.

Does anyone have an thoughts on what I could be missing for Windows Phone 8?

Thank you kindly for your time.
