Hangs with Custom Resolutions

[anti-trend]

After tweaking the config file to set the resolution at 1680x1050, the game hangs during the introductory narration with the envelope in the background. If the narration is bypassed however, the 3D gameplay functions as expected. No such hang occurs with the resolutions provided in the GUI, possibly for this reason.
