I'm using the latest version of InDesign CC 2014; I'm working on a relatively simple 154-page document.
When I try to apply a change to a paragraph style, however, the application quits responding and I get the "beachball" until I force-quit. I've tried changing the style within the Paragraph Styles dialog, and changing it in the text then redefining the style. Nothing works.
I also tried exporting the file to be able to be opened in InDesign CS6; that crashed the application, and sent a report to Adobe.
Same issue. Trying to adjust tabs within paragraph styles, ID CC 2014 just hangs there, the beachball spins, I have to force quit and restart.
I've found that it is document-specific; in other words, it only happens with certain ID documents. But I can't tell what the common points are among the documents.
Might be a font problem...
