Maybe it's just me and this particular scene, but I find that I have to scrub the time line constantly to refresh the display so that layout keeps up with the edits. I don't recall having to do this (with the same scene) in previous versions of LW8 (and certainly not 7.5).

I'm on a DP 2GHz G5 w/4.5Ghz ram
ATI 9600 (stock)
MacOS 10.3.5
LW 8.2

Just wondering if anyone else is experiencing this?
