Whenever I try to unlock my file vault, the application freezes.  Sometimes it does seem to resolve whatever issue it's hanging on, but other times it will just stay hung up until I force close it.
This doesn't seem to affect the drive, it's still added correctly most of the time, even when I force close it.  I would still like to resolve the issue as it causes an additional headache each time I have to unlock the vault.  It also makes me a little concerned about the reliability of the tool.
I've attached a screenshot of the frozen app. 
Does anyone else have this issue?  Or know of a fix?
