Peter, is there not an update option on iweb? Software Update should keep this up to date as well. Have you ran software update lately?

.Mac the name is still around in some places. It just hasn't made its way out of the code everywhere. If you are having issues connecting to the server, check your firewall settings too and lastly the preferences for the program to see if anything stands out.

I am not too familiar with iweb as I write all my code by hand, but these are the basic things that should help get you on the right track.
