I am testing my game on two devices, a first gen iPod Touch with 2.2.1 and a 3GS with 3.1. Everything is fine on the 3GS but on the iPod something seems different with the touch handling. I have a menu item image and if I put one finger on it then tap on it a bunch with another finger while dragging the first finger off the button the menu will become unresponsive, I think a touch never gets the TouchEnded call so then the menu is still waiting for a release. It is not a huge bug as it seems to be fine on the new OS and it takes a seemingly random amount of events to trigger it, but it is still a problem when the game seems to be unresponsive.
Has anyone else experienced something similar to this?
