Try hitting the minus key (-) on the number pad. That should take the scene offline and use the Effect Out set up in the transition logic tab. The TAKE key is used to resume pauses on the main scene director. In the past many people would put a pause on the main scene director followed by the effect out (and you can still do that), but it doesnt use the transition logic logic in that case.
Think of the situation where you have a full page graphic with a number of bullets to animate (say 5).. If after 3 bullets you decide you want to lose the graphic with the transition out, you wouldn't be able to hit ENTER as that would resume the next bullet instead.. So the MINUS key will take the graphic offair using the out transition.
Hope that helps...
