This has happened on my iBook ever since I got it. In Panther, and in Tiger. Also, it happens on all Internet connections I have put it on. I can say Load about 6 or 7 Tabs all with different web pages, and the site I chose first will have to completly load first before it will load any of the next tab. So browsing multiple pages at one time does not go well with my iBook. What is the cause for this and is their a fix / tweak. Firefox (which I really dont like for the mac) works fine just the way I want it to, and will load all pages at the same time.
