I'm listening for that notification. Sure is a clunky way to do things. I've never used a view framework that didn't tell views when they became active/inactive.
I'm not sure viewDidMoveToWindow works here. I'm using it already for something else, and it gets called 3 times when my window is created, but never when activated.
