[Zope] Netscape 4.7x Redirect problem

Hello All... Trying to use a RESPONSE.redirect('menu') on an intermediate page for handling logins. After userid and password and submit, the loginCheck page does its thing. If really a valid user, the code above redirects to the main menu page. Works great in IE but I get "Document contains no data" for Netscape. Has to be the redirect because if I comment it out, the other parts of the page display correctly. Any ideas?? Thanks Allen
