UI font wrong in InDesign CS6 after Mavericks upgrade

Question

This is a tiny but niggling issue with InDesign CS6 post upgrading to Mavericks.
After upgrading from 10.8, palettes and drop downs that used to have their text in regular weight Lucida Grande now have them in something slightly less legible (maybe Geneva?). The bold Lucida Grande (e.g. when you have a swatch or paragraph style selected) is as it always was, but somehow the regular weight is gone.
The main dialogue boxes and windows also all work fine, it's just the palettes and drop downs etc.
Illustrator CS6, Photoshop CS6 and Bridge CS6 also seem as they were under 10.8. InDesign CS4 and CS5 also unchanged under Mavericks compared to 10.8 – so only InDesign CS6 has the problem as far as I can see.
Have tried it on two Macs and had the same experience.
I did read that Apple had introduced a new version of Lucida Grande with four weights instead of two, so I wondered if that had something to do with it, but Font Explorer on both Macs I've tried only show two weights of Lucida Grande. I did try reinstalling Mavericks in case I'd accidentally deleted something, but that made no difference.
Anyone else noticed this?
Thanks!

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!
