Between Sep 1, 2009 and Sep 30, 2009 we published the following HOTIFX articles\files and knowledge base articles:

Knowledge Base Articles

• 976184 - Empty groups still appear as available selections in work item fields in Microsoft Team Foundation Server

HOTFIX

• 975001 - TFS: Duplicate items created in Project Plans causing slow responses
• 974804 - Excel integration crashes when trying to 'get' new list of items

At time of writing these two HOTFIX articles have yet to be published and the fixes themselves are not yet available for download from Code.MSDN.com, though they should be soon. If you need them in the interim please open a support case with us. The case will be free of charge, we just need the case in order to track or work.
