fxfactory, thanks for the huge update. That all makes a heap of sense, and while I'm not planning to send you anything Vuo based in the near future, once the bugs are ironed out and it seems like a safer option, let's chat. :)
Great — thanks for tracking that down. My Mac does change monitor setup quite a bit (laptop into TB dock with monitor connected) so a bug related to that would cause issues. Awesome!
