I found that if you put your Neat library into an encrypted (version 2.0) folder, it will hang both Neat and the system. It has always worked flawlessly using Boxcryptor Classic. I'm running current versions of OS X, Neat, and Boxcryptor for Mac. Really inconvienient to now have to run both the new version and the classic version just to get Neat to work.
Anyone have suggestions or similar issues?
