Ed--
From what I see on the Forum end, you've posted from 4 IPs. None of them match any banned IPs that Chip, Xine, and I control. However, I think that the IM feature operates independently of the forums. However, I don't believe it is a sophisticated enough program to block any IP. In fact, I think the whole IM thing is very buggy and needs some universalization. For instance, I can't use it in the Safari browser at all--it posts prematurely--and when I use Explorer, it often posts everything I write twice...at least on my end.
However, your particular issue sounds more like a problem with your machine than an Adagio/IM program issue.
I am not a computer genius by any means (for that, see EO), but if you run from a Windows machine, try doing a quick system restore to a date just before you noticed the chat snafu. If you still notice the problem, try
e-mailing Adagio.
