i think i figured it out. for me the key is to drag to the edge of the screen (doesn't have to be the corner) SLOWLY till about half the icon disappears off the screen, and then just HOLD it for a second, and it moves to the next screen.
i was doing this thing where i'd slide it and it would bounce back and not move to the other screen...guess it was moving too fast.
ah the learning curve of the new OS. thanks for the tips guys...
