It appears, then, that I haven't implemented the Registry change correctly then, as no such code appears in the Terminal :( The problem is, I've no information as to how to create this particular registry entry. My options, after right-clicking in the OpenGL Key window, are to create a new String value, Binary value, DWORD value or Multi String value---which is it? It doesn't appear to be Binary or DWORD as they appear to only accept numerals as input. If it's Multi String Value, do I hit enter after creating each GL_ value or simply leave a space as advised in the wiki?
