Yes, cybergraphx.library function is used so it's required.

Okay, so on my A1200, I have tried CGX v4 (full install from the original CD). I've tried V3 from aminet, I've also tried the CGX install from the both the OS3.5 and 3.9 CDs, and no dice. Always the same cannot find cybergraphics.library v37. None of them show as v37 - all show as v4x.xx etc. They are all called cgxsystem.library. Can you tell me the exact file I need and where I can locate it, as I'm clearly doing something wrong?
