When I try to select 1920x1200 for full screen (It is highlighted) a check mark is placed at 1920x1440 (which my monitor does not support.) Then if I try to switch to full screen dom3 crashes:
SDL_SetVideoMode failed: No video mode large enough for 1920x1440
Något gick fel!
Resolution change failed

Resolution change failed
Using "dom3 --res 1920 1200" works. So just the preferences screen has a bug.
