Do you have an OS X version of QT Pro? If so, what's its path?

That's ridiculously slow... something else must be going on. Rev is
really fast at this kind of stuff. When you say "become active", do you
mean that you initially have them in a disabled state and then it takes
the time to re-enable them? Can you please clarify?

Sorry, can't help you there (video's not my strong suit).

Sure, the "export snapshot" command allows you to do this, but this was
introduced in Rev 2.1, so you'd have to upgrade to get this feature.
