I said that I go to http://www.photopost.com/members/forum/index.php to htaccess and
vB login, and then can access the http://www.photopost.com/members/members.pl member area according to the htaccess info I entered (without open/close browser) but I still need to login again if I wish to download a script.
katipo goes to https://www.photopost.com/members/members.pl (login_1) and then http://www.photopost.com/members/forum/index.php (login_2) and then
vB login to forums (login_3). I doubt it has anything to do with the canned Norton/cookie answer. The double htaccess login might be related to /members versus /members/forum so order may matter.
Edit: It has to do with http:// versus https://
