Strange Problem with NS6.1

Hello Everyone- I just created a website http://www.krox.com and in Netscape 6.1 it does something strange. When you first come to the site it hits index.php which sees if you've visited the site before or not via a cookie. It also checks that cookie to see if you choose the enhanced site or the light site and send you to the appropreate page. However, if it's your first time to the site you hit a splash page inorder to choose which version you want (either light or enhanced). In NS 6.1 it sets one cookie in the index.php but when I try to use a redirect page to set 2 other cookies and then use the header() to move to the next page in NS it doesn't set the 2 other cookies. I'm just curious if anyone has any ideas why it does this? thanks, jay
