LR4.2 annoyance

Adobe have for whatever reason chosen to disable the live crop preview on a second monitor.
What I mean is if you have 2 monitors, use one for making the changes and the second for viewing in full screen, the second monitor use to display crop changes as you cropped which was brilliant, but now you have to "apply" the changes before seeing them on the second monitor, I have no idea why this has been changed but as far as I'm concerned is a real step in the wrong direction.
Has anyone else noticed this, is there a option to enable it that I haven't noticed?
I do a lot of post cropping and find it most frustrating. The real annoying thing is the 4.2RC version still showed live cropping, this has only happened with the final release!!

Thanks for that.

That's interesting, maybe I need to do a reinstall, something may have corrupted when I upgraded from the 4.2RC version.
