The first time I use the Move Item Action and begin a move I get a null reference exception. It doesn't happen when I use a controller to move the item around or the keyboard WASD to move it around. It only happens when I move the item with a mouse drag. The problem seems to be that the itemViewDropHandler.DestinationContainer is actually null for some reason. I just updated UIS to latest release hoping that would solve it but it didn't. Any ideas on what could cause this?
