Hi,

I'm trying to attach my signature from the OpenPGP -> Attach menu, but
it is... inactive. I have to do that manually and then everything is OK,
but i'm too lazy to do that every time I need to.

OS: Mac OS X 10.5.5
Thunderbird 3.0 Beta 1
Enigmail version: 0.96a (20081204-1941)

I have generated my key manually (not using Enigmail), but this, I
believe shouldn't be an issue. Tell me if I need to provide more
information.
