Warcraft 3 Frozen Throne Full Screen?

WC3 is a 4:3 ratio game, and even though the resolutions supported allow for WS gaming, I would like to play it with BLACK BARS on my Macbook Pro.

Before you start telling me how about it does work on WS, I have a Dell 2707 hooked up to my PC. Yes 1920x1200 works on WC3 but honestly, the units become stretched out. Text looks fine but everything is stretched. Solution? I play at 1600x1200 and my Dell 2707 allows for the scaler to be off so the black bars show up. Result? I get black bars but the image is the way it's meant to be.

Any way to do this on my Macbook Pro? I don't plan on hooking a monitor up, but I want a good image on the screen. While gaming on my PC is still amazing because it is a gaming rig and what not, there are times I'm lazy and I would rather play in another room where my MBP is sitting.

Thanks in advance!
