The Cross-Reference Format is blank in the New Cross-Reference dialogue box. It should be showing options such as Page Number, Paragraph Number etc. I am used to seeing them there. But in this project it is blank. I can select the paragraph style, and the paragraph I want. But if I click on OK to insert the reference Indesign 5.5 crashes.
I use cross-references a great deal, and have not had this problem before. It seems unique to this particular file. Incidentally, I created this file using the Blurb Book Creator plug-in. That is the only thing I can think of that is different from my normal practice.
Did you try to clean up the document with IDML-Export?
Yes - but unfortunately it does not remove the problem.
I decided to test whether the problem was caused by the Blurb Book Creator. So I created a new book using the Blurb Book Creator, added a text box, and inserted a cross reference as the first thing I did in the new file, and the same problem arose. I do not know what Blurb have done to create this problem, but I have now left a message about it on the Blurb support pages of their website.
Thanks for having a go.
