So today InDesign (CS5) decided it would not show my paragraph styles. In fact, it doesn't show any of the icons that normally appear at the bottom of the paragraph styles palette either. Tried importing styles from another document, and they will show up if I go to the pull down menu under New Paragraph Style > Based On, but they don't show up in my Paragraph Styles palette. And the Characters Styles palette looks just fine.
I already trashed my preferences and relaunched InDesign, but this didn't solve the problem.
Any other suggestions?
