I have the same issue with EasyABC 1.3.8.7 on Win 11 new laptop. The ABC code text itself displays crazily upside down and reversed and with unusual colours. Music notation is fine; just the ABC text is off.
similar issue here.. Win 11 ver. 1.4.0.0 The program opens but not before the message, "Warning: pygame/pypm module not found. Recording midi will not work" pops up. I cand I can load a tunebook file, but only some tunes will play sound. Most tunes will not play. I am puzzled here.
