Hachim:
Yes, the standalone version has the same problem.
In fact, I just noticed that the messenger on your site also has the same problem. I'm logged in to your site and when I open messenger, neither my username, description nor contacts are populated.
Do not know if it helps, but I have also the same problem on the messenger on this site (link at top to the right). My credentials are not "transported" and when clicking on the "My name", and "My description" the java script error occurs. I use XP with IE7
