Have already trashed preferences. No effect. Also crashing every time I try to change a parapraph style (which is why I'm trying to export to IDML so I can go back to using CS5.5). So looks like a large book project for a client is stuck in InDesign CC. (Even tried copy and pasting - just get the spinning beach ball.)
The document I imported into CC has some missing fonts. Can't fix those either; when I try to use the Find Font dialog, spinning beach ball when changing the missing fonts.
Any solutions?
