Mirror's Edge (Unreal Engine 3), Win7 x64, DF v4.3 Pro & Beta 5

If I force the EXE to start up on my secondary monitor via "Window Location" it properly throws the games splash screen up, but when it goes to its "Loading/Intro" screen (and subsequent) it flips back to my primary monitor and cannot be moved.

The game does not have "windowed" or "borderless window" options. I can Alt-Tab out of the game, which minimizes it, but I cannot Alt-Enter to make it windowed.

Is there a way to force all windows generated by an application to stick to a particular monitor?

Okay, thanks Keith. That does help.

I have been using the DisplayFusion Monitor Configuration feature to switch the #2 monitor to Primary and that works, to a point.

The problem I have with that is the desktop icons always get stuck on the #2 monitor when I switch back to the #1 monitor as Primary. And it stays that way. The Start/Task bar and Sidebar Gadgets revert back to the #1 monitor fine, but not the desktop icons. If I unplug the (HDMI) secondary monitor then the icons flip back to #1 (except their placement is now all screwed up) and everything's functionally back to normal... until I plug the #2 monitor back in whereupon all the desktop icons pop back over to the #2 monitor (though the #1 monitor is still Primary and still has the Start menu and Windows Gadgets.)

If I can get the desktop icons to behave (revert) properly then I would consider this problem resolved, just not ideal. If I can't at least get the icons to move back and forth between monitors properly while maintaining their original placement... then I'm afraid I've bought a program that doesn't fulfill my needs (forcing games off the little laptop screen onto the big wall screen) :/

Any thoughts on the icon issue?
