The NAL windows has a strange problem.
If it is placed on monitor 2 and you move from the dockingstation to somewhere else, it will still be on (the misssing) monitor 2.
The "Move" function is not there when you right click it, and closing down the program will only bring it up on monitor 2 when you start it again.
Only a reboot will bring it back on monitor 1.

Is there some setting you can tweak for this?
