I have tested on your sandbox: Here is a small video that presents the issue: http://www.youtube.com/watch?v=6VoVKeOy9dg&feature=player_embedded(sorry for the quality, but I'm not Spielberg). I can observe that the pinch function is working, but the browser window moves. I don't observe that on the iPad 4.2. If it's an iOS version issue, I don't think it's so important. > > > - Android Nexus S: the double click seems to work a bit better, but has >> still issues.

So the tolerance should be a bit bigger.
