I have a 4  monitor setup.  For various reasons, I have certain apps which are always on top on the primary desktop display. 
Galciv 3 always opens on this display, so these apps are always on top.
How can I tell Galciv3 to use a different monitor?  They all have the same resolution, so that isn't a problem.
 
Is there a command-line option to specify a display?
 
For the record, this is a Windows 7-64 bit system, 16 gig memory, nVidia GTX 760.  Each monitor is an HD monitor with a resolution of 1920x1080
 I am running in non-fullscreen mode, with a display resolution of 1920x1080
 
Thanks in advance
