1. yeah i am setting up the views in IB.. just the interfaces though,
all the code associated with the views are in their respective header
and .m files.
2. i did create seperate subclasses for each view (view1 and view2)
which are subclasses of NSOpenGLView in IB. I did not instantiate the
subclasses though....just specified to the view widgets that they each
had a different class ("custom class" from info window).
thanks for your feedback. i will look into initWithCoder, but what do
you mean by "you can later change their actual type to an instance of
your custom class with the inspector. " ?

Well, are you setting these up in IB? Views stored in NIB files
created by IB (except for the custom NSView) are not initialized by
calling initWithFrame: but by calling initWithCoder:. Also, do you
mean that you have one instance of each of the sub-classes (of which
there are two), or do you mean to say that you have one sub-class
instantiated twice?
Usually this kind of problem is an IB issue related whether or not you
created the views as NSViews or NSOpenGLViews. In either case, you
can later change their actual type to an instance of your custom class
with the inspector. The difference being the way that the views are
initialized at runtime when the NIB is loaded.
Hope that helps,
Jeff.

I'm making an application using Cocoa-OpenGL. i have 2 separate
subclasses of OpenGLView each having their own initWithFrame
function, but the second subclass never executes the code inside it's
initWithFrame function. any help/tutorials/examples would be
appreciated/
Thanks,
Aaron.
