Android Question Gesture Library swipe not working when swipe starts on a button

[505sw]

I have tried putting a transparent panel over the buttons but the gesture sub does not get called when the swipe starts over one of the underlying buttons. The buttons are drawn during program execution so I always place the panel on top afterwards. I made the panel semi-opaque to test this and the panel is definitely on top. Swiping the panel returns the correct coordinates, but if there is a button located underneath and the swipe begins over the button, nothing happens. What am I doing wrong?
