I also have the following behaviour:
If the MultiTouch is active then whenever I touch the screen the system does not get the "button release" event when I lift my finger off the screen. thereafter I can move the mouse with any of finger, stylus, trackpad, trackpoint, or external mouse, but left button presses/releases do not register at all. Sometimes I can regsiter right button presses but not always. Is there a parameter here I can change to be more sensitive to lifting my finger OFF the screen:
Code:
