Issue I367 [80,commandline,resolved] Command-line errors not always displaying/trapping. Prior to 8.0.3, errors when invoking SIMION from the command-line would not always display, particularly when "--nogui" is not specified. Prior to 8.0.3, running "simion.command('fly --help')" inside SIMION GUI mode would cause crash (error message not handled). This is resolved in 8.0.3. Affects: 8.0.0-8.0.2 Resolved in 8.0.3.
