This has been driving me crazy so I wanted to pass it on.
Since I have installed Fusion I can no longer view PDFs with Apple's Preview when I export a PDF from InDesign CS2.
Response from Extensis:
This is something we have noticed with Fusion, and we are investigating it now. There is a workaround: In the preferences for the Suitcase plug-in, disable the FontSense option and your PDFs should work fine in Preview (you can always turn it back on after the PDF is exported).
As soon as there is a permanent fix or a more effective workaround, you will see that information posted on our website.
