I have had to rebuild the same book chapter three times this morning because after I update the TOC for Figures, then save and close the file, I can't open it again. InDesign tells me either the file is already open or that I don't have permission to open it. Through trial and error I have isolated this as the problem. It builds the regular TOC just fine, and the TOC for Tables, but when it builds the Figures TOC, it's game over. Anyone else having this issue?
