Playback stops at end of timeline selection?

[Blank Frank]

Is it normal that playback stops at end of a timeline selection, I seem to recall that PT7 didn't do this. I find it really annoying as a lot of times I like to work on a loop then play from before the loop until after the loop, but then go back to the loop. It seems like now I have to clear the time line selection to do this. then reselect it again, (drives me almost as nuts as the fact you have to stop playback to turn page scrolling on and of, and that there no key command for it either, better stop there or I'll be here all night!!!). Anyway, back to the point in question, is there any option to make playback independent of the timeline selection? I can't see one.
Any help would be much appreciated.
Thanks
