WordPress or mozilla Login redirect bug?

With a new WP2.0.1 install I’m having trouble with the login redirect page using mozilla 1.7. After loging in I get a white page with nothing at all nada! Using the url wp/wp-admin/ I can get to the dashboard and everythiing works fine ans the site and posts too.
Logging out gives the same white page and no redirection to the login form page.
Trying the login logout procedure with IE6 and Firefox 1.5 redirects works fine page load no problem.
I found login problems but not really browser related or…?
