Bing Map Windows Phone 7 Pinching

I have a map view that works well, pinches to zoom in and out and pan around.

I then call a detail page...

 NavigationService.Navigate(new Uri("/DetailPage.xaml", UriKind.Relative));

And then开发者_高级运维 go back to the map pressing the back button. After that pinching is disabled to zoom in or out. I can double tap or pan around but this doesn't seem right?

Thanks to a legend at MS the October 2010 Dev tools update fixed it!
