I don't know what device you are running on, but on things like the G1 and myTouch, the touch screen isn't able to accurately detect locations at the far edges of the screen, so when you reach that area the location will be pinned to the very far edge and the flag set. Note that this is referring to the edge of the -screen-, not wherever your view is.
