@codered78: After you move down to select the first piece, you can't move anywhere else, as it's the only valid piece. Press the "enter" key to actually move.
@mrobert: on that note, pressing the trackball in, should probably activate the move as well. It took a while, before I figured out it was the enter key. I had actually finished typing the same message as codered78, before I decided to try again.
I can use the up/down on the trackball just like a trackwheel. It would just be nicer, if the left/right worked as well.
So, at this point, there's only a 100 move limit version available?
