I think this is the first time i see a thread about anyone disliking the fact that the mouse isn't trapped in the game. If they changed it so the mouse-pointer is stuck in the window without adding an option to turn that off, i'm sure there would be at least as many complaints about it in here. I don't want to run in Windowed mode either, my friend has Resolution options, I'm lanning around his as I type this. Some games have the better function where you hold down the right mouse button and pan the camera by moving the mouse. It's slow to get you where you want and takes up a lot of time (when you combine the thousands of times you do this during one match) that you could have used commanding something. Using the mouse for edge-scrolling is kind of old and inefficient. Select windowed mode in video options (Steam only) or use the WINDOWED. I also play in a a window, but turning off edge-scrolling and only using WASD actually is actually better for me as i can move the mouse to any other application (which happens often) without having to AltTab while at the same time control the game-camera faster than when i only used the mouse. Star Wars: Empire at War - Gold Pack comes with both the base game and the Forces.

I don't remember if i changed it myself before or if Rebellion added this by default, but WASD works like the arrow keys for me. You consider this a problem? Well then here's a tip for you that not only solves it for you but that makes you more productive in the game:
