I'm not sure of the "why," but I have encountered this as well.
I've been able to work around it by drawing the border using [self
bounds] rather than the rect variable that drawRect: gets passed.

I'm getting some weirdness with NSViews and subviews. Here's a
screenshot of what I'm talking about.

Check out the box around the button that says `Finish'. That
border draws when I press the button, and it refuses to go away.
The button's superview, is the box with the 1.5 pixel-thick
border, which I draw with an `NSBezierPath' in the `drawRect'
method. I've run into this type of thing before, and putting a `
[view setNeedsDisplay:YES]' in the right place does the trick. But
in this case, it's not working.
Why are the subviews apparently using the superview's `drawRect'
method when they're dirty?
More to the point: Does the box drawRect: stroke the framing
rectangle based on the NSRect passed to it? So that when the button
region is dirty it frames the button?
