>>Say there is a map with 5 nested levels of replies in the top window, and you click on the outer nested message to read it. Then you click on the Next button 4 times, so you read all 5 messages. But only the top level message shows a followed link color change in the top window in IE. In Netscape, the followed links all change color as you read each message.
>>So in IE you can't tell which messages you've read and which you haven't in the top window using the Next button, so that it isn't very useful. You need to actually click on all the top window messages to show them as being read already. Does that make any sense?

I do like Netscape, but as you've no doubt read the messages on this, it crashes too many times now for some of us when we use it. Hopefully either MSIE will add features or Netscape will become more robust...
