iPhone - Issues with ClassEInput::ClickHold()

Hi! I'm having some problems when using the ClassEInput::ClickHold method. More precisely, the method sometimes returns true even when the screen is not being pressed.
In order to analyze a working example to modify my code accordingly, I've compiled and ran the multitouch example provided with EDGELIB in my ipod touch and found out that is not working as expected: if I touch the screen once a red square appears but, if I remove my finger from the screen, the red square still gets rendered instead of disappearing. Can you check that?
Thanks in advance for your help!
