Ok lets try this again ... you said I should try 1920x1600. 1920x1600 is a 4:3 resolution not a widescreen 16:9 which is what my monitor is, so obviously I can't run it.
That should make it pretty clear that it's a 16:9 monitor, for the sake of extreme clarity my monitor is a BenQ G2401HD 24 Inch 16:9 which runs at 1920x1080. Running the game at this resolution or any resolution other then 1024x768 results in a lack of comms menu and other distortions, this was the same case when I ran the game at 1600x1200 on my old 19inch CRT 4:3 monitor.
