U3DXT share sheet freezes screen

When i implement a button that creates a new share object, it show the share sheet just fine, but if you were to press cancel or tap elsewhere on the screen, share sheet goes away, but the screen is frozen and nothing works/is being detected. Although, on the share sheet if you were to start a new message/mail/etc., and then press cancel, you can continue just fine.

How do you make the screen not freeze when you press cancel on the share sheet in iOS 7? I had already tried to restart the scene on the OnShareCompleted() method, but nothing works, please help!
