its just the post mouse generation, I see it all the time, and there is nothing really wrong with it ... until you need a keyboard command
I am sure there are some 12 finger multitouch wizardry that I dont know about, and god help me operating a modern phone, but durn it I can operate windows without a mouse, almost as fast with one!
the reason why is the program (and most java programs) doesnt really handle the context menu, keyboard commands are universal to a point
