is access to this forum page supported by Win 7 IE 9.0.8112?

Any time I try navigating in this forum, I get webpage error, do I want to debug and then I click No.  I cannot reply to messages.  The reply icon is not there.  I moved over to a XP box and then I could find the reply icon (and edit ones as well).  This happens whenever I click anything on this page... I cannot insert the popup box image (too large).  The error says it is line 260 and "container Type' is undefined.
