Hmm, I've got NIS too, but it's 2003, but like Gigolo I haven't come across that prob. I wonder why it would change your theme from page to page though.
What I can't understand, is that I am running an identical configuration on my work computer, and I don't have this problem....
Hi,
Better try McAfee Virus Scan Professional with fire wall, works brill!
Its the script blocking, if i recall it right there is a bug in NAV2004 making the script deleting your usefull cookies, cause the scanner is programmed all wrong, i suggested you try look for an update, or state for an bug update on their homepage/email/customer service
