Blender Crashes

I have just downloaded Blender on my powerbook G4 titainium running OSX 10.3.5 It will start up, a window appears, but then the porgramme crashes. Help please!

Your OS should give you an error message which would point to the problem, most likely your graphics card or OGL.

Try setting the display to thousands of colours and see how that goes.

thank you - changing the screen resolution did the trick
