Hmm... doesn't help, when i click off of the AFX app, the Preview stops.
perhaps Im not explaining clearly what Im trying to do..
Lets say i load an animation effect onto a solid... I want to see the preview, but of course the frames have to be rendered to see it at real time..
so... U click preview\play.. it starts rendering states, right.. but.. as soon as u click anywhere else on your screen.. either in or out of AFX.. it.. stops.
Basically.. unless u sit here and just watch your screen as the it renders ur preview across the timeline...it stops rendering the preview.
