Question:

I am unable to put the Microstudio Play Window on the Second Monitor.

Answer:

The Microstudio play window only appears on the primary (host) display, and does not allow me to postion it on the secondary (singer) display.

This Feature is no longer available in Microstudio.  This was removed in Microstudio 2.613.

Microstudio will only allow using Single Display, to allow you to check your Discs.
