Hi Graham, Thanks for your help, I've implemented your suggestions and it's working great, I just have one quick question if you don't mind.
I'm new to Objective-C as you've probably gathered and am not 100% about how the memory management works. Will I be causing a memory leek with the line: path = [[NSBezierPath alloc] bezierPath]; within my initialiseBezierPath method? Thanks for your help, Billy.
