Psi blocks entry to the chat window input area during encryption.  The whole 
app, however, including the rest of the chat window, should remain 
responsive.

The reason input is blocked (the input area grays out) is due to a number of 
issues, for example what happens if the gpg operation fails?  Currently it 
will just ungray the input area, with your original message intact.  Things 
get ugly if you allow inputting another message.  Anyway we may improve this 
somehow in the future, but I hope you can see the rationale for the current 
behavior.  This behavior has existed since the first gpg-capable release of 
Psi (some three or four years ago, 0.9, I believe), and nothing about this 
changed in 0.11.

Since the bug reporter claims the freezing was not a problem in 0.10, I 
suspect he's talking about something else (an actual bug as opposed to 
intentional Psi behavior).  Maybe the reporter can reclarify what is 
happening.
