Note, however I am having trouble with Lesson 3 (adding colours to the triangle.) It keeps crashing on me. To make sure I didn't mistype something, I did a full copy and paste of the drawView function and it is still crashing.

It seems to be related to setting the colours, if I comment out the one line "glEnableClientState(GL_COLOR_ARRAY)", then it runs without crashing (but of course, the triangle is still white.

Note that I followed the template exactly as described and lesson 2 was fine.

Thanks a lot for any help!

As an update, Lesson 04 works fine as well with the triangle rotating, but again, I need to leave the color line commented out or it crashes.
