InDesign Freeze when "Packaging" files.

Question

New Mac with Snow Leopard, 10.6.6 Just updated to CS5. "Packaging" will not complete on some documents (at least two files so far) if I ask it to gather the fonts as well. The same files works fine in CS4. Fonts are not protected.
I use FontAgent Pro 4.0.3 to handle fonts. I've flushed all font caches with Cocktail 4.8. Still no cigar.
Anybody else seen this behavior?
Thanks.

Answer 1

I am getting the exact same problem. Upgraded to 7.0.3 as well. Packaging my current document always freezes InDesign, and upon restarting it opens two versions of the same document as though there are two separate aliases. Packaging progress gets just to the very end of the progress bar, a folder does get created with the links and fonts subfolders, and an INDD file is created (but cannot be opened). InDesign doesn't budge once the progress bar freezes, and a force quit is required. I've been able to package several others prior to this in the past week. I'll try a few things with the document itself.
