Cases where this occurs are rare, but when it does the generated DVI file will be invalid. The DVI files produced by Omega may use extensions which make them incompatible with most software designed to handle DVI files. In order to print or preview them, you should use odvips to generate a PostScript file.
Omega is experimental software.
