Never mind. Figured it out.
I guess while I was setting up the cookie names, a cookie was setup for each domain name on my workstation. I run talk forum at surftalk.njtackle.com, photopost at photo.njtackle.com and classifieds at classifieds.njtackle.com. Problem is I only want one cookie for entire domain .njtackle.com. Once I deleted each cookie for each subdomain thru MS explorer (surftalk.njtackle.com, photo.njtackle.com, & classified.njtackle.com), it re-created one cookie at njtackle.com that is used for all three and the login/logout feature works as designed.
Cookies can be a real pain in the arse sometimes.
