David, Yes, I noticed this clicking problem with JOSM myself, and it is annoying. Is it Java or just JOSM-specific problem? In OS (Windows at least), the mouse-down and mouse-up events are treated separately, so I don't see why it would be problem if the mouse moves in between. Anyway, thanks for the info. Looks like I'm going to have to borrow a tablet and test it out with JOSM before buying.
