The Matefish 2.0 has significant problems with the Arena GUI. According to the programmer, the program should be started in the console. With this it worked. Thanks

The Matefish 2.0 has significant problems with the Arena GUI. According to the programmer, the program should be started in the console. With this it worked. Thanks

That's not exactly true.
Matefish 2.0 works just fine under Arena.
