It’s a strange one Martin, we have just tested it here from a Windows 7 machine and can confirm it should work. 
When you use the activmanager to calibrate, does it swap between which screen you can control with the slate?  
(Right click the ActivManager icon –>  Calibrate it should prompt you if you want to calibrate your slate.)
