Hi,
Has anyone experienced issues with their CS5 timeline becoming laggy and/or unresponsive with one or more tracks locked (either audio or video)? Mine becomes very slow to update (1 to 2 seconds) and often tracks become visually out of sync when I move along the timeline (not scrubbing the playhead but using the bottom bar). i.e. - all non-locked tracks move/update but the locked tracks stay put or jerk and end up out of sync (they refresh once unlocked and "snap" back into their proper place). Playback can be but is not always effected.

I've not seen this on my own system. I don't recall others reporting it here in the forums, either.
My only guess, and it's kind of weak, is a graphics card issue. What model are driver are you using?
