Been there first, saw that, it's a blind alley. This is where it happens when you .send() - I'm getting this at instantiaton. Which is why I think it's either a misleading error, or the genii in Redmond thought that nobody would ever use XML without writing a web server or a web client. Which I'm actually doing, but the xml parser is used only to prepare the string to send, it does nothing with the connection. For that I use wwHttp alone.
