Hi Thomas,
        Thanks for finding a protocol bug. I apologize for all the trouble
this caused you or anyone who downloaded our software.

We have posted an updated version, which I hope resolves the issue.

We have changed the client negotiation to use iq:browse as you suggested.
The message flow is now

cross client inter-op. That's the beauty of an open system like Jabber.

It was not our intention to create spam or break an open system. The reason
this bug slipped thru was
a) not testing with WinJab
b) we learnt most of the Jabber protocol by looking at the XML over the

We plan to correct this ASAP, but some lessons are always learnt the hard
way ;-)

Once again thanks for your feedback and sorry for the trouble.
