You can report bugs and problems with XBoard using
the bug tracker at https://savannah.gnu.org/projects/xboard/

WinBoard development section.
Please use the script program to start a typescript, run XBoard with the ‘-debug’ option, and include the typescript output in your message. Also tell us what kind of machine and what operating system version you are using. The command ‘uname -a’ will often tell you this.
If you improve XBoard, please send a message about your changes, and we will get in touch with you about merging them in to the main line of development.
