I've not noticed it.
Can you make screen captures and post with the camera icon in the editor.
Yep, here's one of the swatches palette in CS6 and the print dialogue in CS6; plus the same two in CS5 on same machine.
On the CS6 swatches, the unselected colours aren't in Lucida (the 1's don't have the bar at the bottom) but the selected swatch is. In CS5, all in Lucida.
On the print dialogue, it's just the white panel on left of box which has always been Lucida before, as it is still on CS5 grab, but changing to something else in CS6.
Blink and you miss it!
CS6 print dialogue:
Compared to CS5:
Here's what the Swatches panel in InDesign CC looks like under Mavericks:
No problem, right?
Remember that InDesign CS5 and CS6 are Carbonized applications. With InDesign CC, the entire application had to be rewritten as an up-to-date Cocoa application, as well as made 64 bit.
So my guess is that Apple doesn't really care so much about the old Carbonized applications any more, and maybe didn't take the same care when they changed their UI fonts.
So I think you're stuck: Getting Apple to change its UI fonts is just about impossible. It's also highly unlikely that InDesign engineers are going to devote engineering time to fixing it in CS5 or CS6 because it's a cosmetic change, not mission critical.
I think you'll either need to update to InDesign CC or live with it.
Thanks Steve. Yes looks good in CC. We'll upgrade eventually (though I often end up using older versions anyway as that's what clients have). Not a big deal with the font, just offends my eye! Oddly it briefly worked as it should after I posted my last post, but then reverted to form…
