Unexpected behavior after login

After logging into the site, without allowing the site to remember my login, I click on the "My Posts" link and get taken to http://www.linuxquestions.org/questi...archid=####### which reloads about every 10 seconds. While it's reloading, it looks like I have been logged out (As the Login and Register links are back), but the banner at the top of the page says "You have been logged in as <Username> using your Questions Network account."

Steps to reproduce:

1. Browse to http://www.linuxquestions.org/questions/lqlogin.php
2. Uncheck "Remember Me?" if it is checked.
3. Enter username and password in respective fields.
4. Click "Log In" button.
5. Upon logging in, click the "My Posts" button.

Observed Behavior:
"My Posts" page reloads about every 10 seconds with a floating banner at the top of the page that says "You have been logged in as <Username> using your Questions Network account." If you click on any of the links back to the forums, the behavior stops.

Expected Behavior:
Upon clicking the "My Posts" button, I expect to still show as logged in with just the last 50 posts I've made showing in summarized form.
