Try using a PC.
Not sure if I am stating the obvious, but can you close all processes that you are not using and then retry?
I'm also having this problem. Every now and then (probably with a 5-10 min interval) Flash CS6 freezes for 10 or more seconds. The larger the Flash-file, the longer it freezes. I've turned off the auto-recovery mode, I'm not working on a file that's in a network folder (like Dropbox, since I heard somebody had trouble with this), and I've quit all programs. Still freezes. I've also got all the latest updates.
It's very annoying, and I think I would've been able to work a lot more if this weren't happening all the time. Perhaps I'll try to import all of the content into a new file?
Any know solutions?
I'm on a late 2009 iMac:
Mac OSX 10.8.3
ATI Radeon HD 4850 512 MB
2,8 GHz Intel Core i7

Oh, I found out what was causing the problem. In addition to the auto-recovery option in 'preferences', there's an auto-save feature that's on by default and set to auto-save every 10 minutes. This explains why it freezes for a longer period of time each time. It's (remotely) located within Modify -> Document (Cmd + J on a Mac, probably CTRL + J on Windows).
Just remember to save often if you uncheck both of these features
What makes you think (s)he isn't???
