    I have justed installed XAMPP at one PC at home, installed WP2.0.4 there which was super easy. Tried activativing some plugins but a few of them failed having warning as “can’t modify header info ….already sent” something like that. When I clicked back button of my FF the plugin was activiated alright.

    What caused that?

    I used to have separate installation of Apache, MySQL and PHP and running WP (earlier versions) on localhost which was OK.
