I'll answer both suggestions here. Rasterman suggests: "if it is just your APPLICATION that needs to not have motion events... then why don't u simply disable it listening to mouse motion events?" Our application's UI runs on top of Firefox - it's a series of HTML pages served from a local web server. Many of our "buttons" are text in HTML tables, and so any "drag event" will highlight the text, rather than "pressing" the button. Also, for some reason, if a user rolls their finger from side to side while pressing a button, it throws the calibration of the touchscreen all out of whack. I think I've also answered Owen Taylor's question regarding the dangers of "click-n-drag" here.
