Hi Brundlefly and Susan,
I've actually wondered about this too...the Left Click Sets Now option works great when the transport is stopped, but not when it's running....at least not on my system. IIRC it's been that way for a while now. Always kinda bugged me but never enough to say anything about it.
Brundelfly, when you try this does it work for you? That is, just open a blank project, start playback and click in the TV somewhere other than the timeline. Does it move the transport?
