Demul aspect ratio?

I was wondering if there was a way to keep the 4:3 aspect ratio on widescreen monitors? You would assume that leaving the fullscreen mode in 640x480 would work but it doesn't. Is there something I'm missing? The stretch looks a bit poor.

Thanks

I didn't even think of that =]

Turned on auto wide on my monitor and bob's you uncle! Cheers :bouncy:
