I've embedded a PDF of a Visio flowchart into a Frame document. I've added a text box over one of the squares of the flowchart so I can insert a cross reference to another section of the manual. The cross reference works, but the xref text comes in larger so it gets cut off. I changed the text to a smaller size, saved the document, and when I opened the document again, the text had reverted to its original size. I've created both character and paragraph tags and applied them to this text, and that hasn't fixed the problem either. Any ideas on why my text won't stay the same size (bug maybe?) and how to fix this? Thank you in advance!
I use the same approach myself, cross-references in text boxes to a paragraph somewhere else. However, I do not have your issue.
In your case it seems that the cross-reference changes the font.
What's the cross-reference format? Are there any character format building blocks in the cross-reference format? E.g.: <emphasis><$paratext><Default ¶ Font>
