Chris, I just tried to do what you described and I had no problem, as long as I was moving a consecutive group of pieces from the tray. When I select a group of pieces by holding down the shift key and clicking on the first piece, then the last piece, I can move the whole group to the board if I keep holding down the shift key. If I use the control key to select a group of pieces, selecting each piece individually, I can still move them all together as long as I hold down the shift key and select the first unit of the group (selecting any other deselects all the other units).
But it doesn't work at all when I individually select random units that aren't grouped together. Hope this helps. Ken G
