Right click is intercepted by Flash and doesn't reach the actual library UI mouse handler. As a consequence, I didn't code it to do anything because it can't even see the event.

If it's locking up, it's probably due to new browser weirdness.

I don't use the embedded library and the external one doesn't do anything, although it could.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
