Hello Python-OpenGL Experts,
I keep having problems with a part of my program. This program once worked,
but stopped working after an upgrade of my system.
Can someone help me get it running again? The problem appears in the initialisation
phase of the program, during the "prerendering" of the fonts.
Thank you,
Frits
