RouteConverter and Mac OS X

[routeconverter]

You've started RouteConverter from the trunk-source, did you?

Please excuse my lack of knowledge.

No problem, I was wondering about the question marks in the window title and thought you've built the program from the sources.

I downloaded the zip file: RouteConverterPrereleaseMac.zip, unzipped it and clicked on the icon.

Please download the .jar file and try @hvdwolf's trick.

Is there any other way to do that and what is a "trunk".

The trunk is the latest version of the source code.
