Sure, I understood that part of the spec, I just wonder whether users 
are conditioned to think that a lock with closed shackle indicates that 
some type of security is in effect, when in this case it is not 
necessarily so. Current use of the same icon elsewhere conveys state, 
not intention.  I doubt very much that users will equate a disabled Send 
button with an inability to get all the right certs. My guess is they'll 
just think the app is busted, again :-(

What I meant to ask is whether the shackle would immediately return to 
the open state (in the case where the message could not be encrypted) to 
indicate that the message was not yet secure. That's what I'd expect. 
 In the case where it could be encrypted, the sound of a good lock 
snapping closed would be a nice addition too.

Hard to say, since it is so subjective, but I'm guessing size, color, 
contrast of the icon in the spec itself. As I said, I don't have 
problems with the lock icons used in the current product (with Classic 
skin, anyway) or Communicator.

If it was just informational, rather than a control, it could reliably 
indicate whether the message was currently 'secure', and clicking on it 
could give further information, such as why it was still not secure 
(haven't set the pref, haven't asked for the message to be encrypted, 
don't have certs for George and Colin,...)  As it is, the icon just 
shows that you have requested encryption, and I'm guessing the closed 
shackle will make people think it will be sent encrypted.

That's the model I was thinking of.  They are much easier targets to 
hit, and would leave the lock and pen icons free to clearly indicate 
state, or provide further info.

I don't think such sign/encrypt icons would show prefs, they would be 
clear affordances for signing and encrypting *this* message.
