Since going directly from OS 9.2.2 to Panther, I’m having OpenGL problems with some software that I don’t have in X native form and run in Classic mode, specifically FormZ. Previously in OS 9 it was fine but can’t handle OpenGL rendering when run via Classic. After restarting in 0S 9, the same apps run fine. Do Classic programs use the rendering engine form the OS 9 System, or that of Panther? Any tips on how to solve this, other than buying a new version of the the apps greatly appreciated.
