InDesign CS5 (7.0.4) run on iMac (OS 10.7.5).
I find that when exporting a document as PDF InDesign suddenly and randomly freezes at some point during the export process.
The only option is to force quit InDesign.
On relaunch InDesign has forgotten all the presets I had saved (eg Document Preset, Preflight Profile).
This happens fairly frequently but I cannot find a pattern to it or an obvious cause.
Thanks in advance or any help anyone can offer!!
