Indeed I am. We're both using Google Talk and XMPP.

I apologize for not mentioning that earlier.

Interesting. That sounds precisely like what's going on. It sounds
like this is an issue with Google Talk and not OTR. My apologies for
the noise.

Do OTR messages include a timestamp? I was thinking that it might be
good for OTR to silently drop authentication requests that arrive
after a sufficiently-long delay (e.g. >1 week) rather than attempt to
interpret them.

Thanks for the prompt response.
