The problem in regards to users having to log on over and over again is caused mainly by "firewalls" and in some cases Norton products. Before log in, disable your firewall or any Norton products. If you're using Windows XP, disable the build in firewall. Also check your browser settings and make sure that it refreshes "everytime" you visit a site.

I was having the same sort of problems and after rectifying the above, all is fine. I use a dial-up connection and to be honest there isn't a great deal of difference from broadband when it comes to "data refresh".

Hope that this will help some.
