Multi display Issue

Hi,

I've created a game that needs to be run in 3-screen mode and I've been using CommandLineArguments "-popupwindow -screen-width 5760 -screen-height 1080" to achieve this.

But I need this program to run in fullscreen on a single monitor as well. So when I hide the "Display Resolution Dialog" and executes the program with the parameters I've mentioned earlier, it always runs in single monitor fullscreen mode. Apparently those parameters only work if you enable the "Display Resolution Dialog" and manually select "Windowed" when starting up.

Does anyone know how to fix this problem or how to automatically select "windowed" in "Display Resolution Dialog" ?

I've also tried to used this (Resource Hacker) http://www.angusj.com/resourcehacker/ tool to change the .exe file. But failed to select the "windowed" check box at startup.

Thanks for any help in advance.
