Discovered a very minor bug while using Linux that other Linux users have also consistently reported.
When you try to change the race picture, ship, or flag, you get an error that reads: Function #1725: Value does not fall within the expected range. This is immediately followed by another that reads (for example, with flags): C:\Aurora\\Flags\error (where my Aurora directory is C:\Aurora)
For the other errors it shows the Races or Ships directory instead. But note the double backslash in the path (\\) between the install directory and the relative path.
This isn't a big issue, and I understand you probably have no desire to support Linux. I'm not asking for a fix. I wasn't going to report this at all, but someone wisely reminded me you were using this also as a learning project for C#.NET, so I thought bringing this up might be helpful to you.
