As from question title, today I am experiencing some problem on the Collider on the main site. Basically, the StackExchange notification/browsing menu is just dead and does not respond to clicks. The user dropdown menu is also dead. Reviewing items just show a white area with no text or review ui (approve, reject buttons etc). This only happens on the SharePoint site. Stack, Meta-StackExchange, Meta-SharePoint all works as intended.
Is anyone experiencing the same behavior? Btw, I am using IE10 (testing stuff, so I am pretty stuck for now).
