Essentially I have a window with a custom view atop a button. What

result is that if I draw a circle at (0,0), it gets drawn twice at
different locations:

What is going on here? Is this buggy behavior or correct behavior?
My code is basically a new Cocoa application with a single NSView
subclass. There is absolutely nothing funny (that I know of) going
on here. That leads me to believe that the behavior is "correct,"
and that I'm just missing something.
For the record, I only want the one call to drawRect:, the one with
the "proper" NSRect.
It sounds like you've somehow ended up with the content rect of the
window as an instance of your custom view class.
How do you create your view hierarchy (i.e. in Interface Builder) or
"by hand"?
