Quote - You should get either a horizontal or vertical bright band down the middle indicating what is too be rendered, and two dim bands at the outside that show what will be cropped.  That's what I get anyhow, docked or not.

Okay, so it's like Vue does.

Still feels awkward though (see my post just above). sigh
I'm just too used to be able to change my frame dimension freely I guess.

It also means that you can't load old scenes made in old Posers which had no fixed render sizes (render into preview window), unless you undock. That's a pain.
