The Aqua HIG recommend against click-through for destructive items, yet the buttons I create in interface builder by default support click through.
I'd like to change that, but I don't see any obvious way of doing that except to write a bunch of laborious code to enable and disable controls as a window receives and loses the focus.

Override your control's acceptsFirstMouse: method so it always returns "NO". See [NSView acceptsFirstMouse:].

Great, but I have a better solution. I've made a class called MFClickThroughDisabler that you just attach to a control in IB and it disable and enable attached control automagically when the window change state preventing click through and giving the correct visual feedback.
If someone want it, just send me an email.
