Hi all,

It's right there; Document size (centimeters, inches or pixels) followed by Thumbnails (including placement as well as rows and columns).

Oh, I see (now). The settings are ghosted out. Didn't catch that; was in a rush, sorry.

Is that the only command that's giving the issue?

Try trashing preferences? (This will reset everything, so be aware of that, but it can help.)
