The iPhoneInput.touchCount is 1 while no touch actually.

I'm using the iPhoneInput class to drag some object, and when i release, the object will come back to its original position. But i found some times the object don't return to his home, although i release my finger. I check the console info, the iPhoneInput.touchCount is 1 while no touch actually. Is this caused by event lost? How can i solve this?

I found it is caused by the touch event lost. So i modify kMillisecondsPerFrameToProcessEvents to 10. It's much better now. At least i haven't reproduce the bug again.
