Problem with "Edit scrivenings" in Full Screen

This is something I’ve noticed since Scrivener 1.10. When I select “Edit scrivenings” and go to Full Screen, some sections of the text are grayed out (as shown in the image below). It seems to happen right before there is a change in font attributes. This never happened in Tiger, which leads me to believe that it might be related to Leopard’s new text rendering system.

Interesting… It might indeed be to do with a setting that is turned on for Leopard. Can you post a case in which this always happens, so that I can recreate it for myself?
Thanks,
Keith
