You should never alter the size of things inside drawRect. The only thing that should occur is drawing.

I know you mentioned that you've called setAutoresizesSubviews:. Have you also called setAutoresizingMask: to set up the appropriate options? Ultimately, all your subviews should be receiving resizeWithOldSuperviewSize: messages. NSView's default implementation of resizeWithOldSuperviewSize: is to use the options set up with setAutoresizingMask:. You can also override resizeWithOldSuperviewSize if you need something custom.
