Re "Apply Name" - no, I hadn't. Because when you change the name, it changes in the list above, so I figured it was done. Apply forces a refresh, which is just what I had been doing manually. But cool, that's... slightly easier I suppose.
I'll keep an eye out for the event drop issue, see if I can produce a reliable repro chain.
Haven't figured one out yet though, and I've definitely been trying to suss out what's causing it - if nothing else so I can do things another way, and stop screwing things up.
