Yep. Sorry, I should have made that clearer. I have a custom NSMatrix class.
It was more by trial and error than anything else that I ended up
over-riding the NSMatrix methods - they were just the ones that seemed
to work.

That sounds nasty. I really just want to post this notification
whenever the selection changes.

That sounds promising, although a bit disappointing and possibly still
a tiny bit hacky.
Surely it shouldn't really be that hard to capture/intercept selection
changes - to have to resort to trial and error over-riding of
selectXXX, et al. methods is a bit irksome.
I'd kind of hoped that I'd simply missed some method that I could
over-ride to cover my broken cases.

I'm not using bindings in this context, although if anyone does know
it might be of interest for the record.
