Hi, Expressive Indigo -
OK.
You did not state which operating system version you are using, OS 9.2.1 or OS 9.2.2 (since there is no version OS 9.2 applicable to any model except the original G4 QuickSilvers, that version can not be on your machine). However, the version numbers for the OpenGL extensions are correct for OS 9.2.2 - there is no later version available.
Make sure that both Apple Guide and QuickDraw 3D are enabled in Extensions Manager.
Make sure that the file Text Encoding Converter is present in the Extensions folder (it does not appear in Extensions Manager), that the folder named Text Encodings (loose in the System Folder) contains exactly 15 files (no more, no less), and that Text Encoding Converter and the 15 files in the Text Encodings folder are all version 1.6.
