Endnote X4 incompatible with Office 2011

Why is Endnote X4 incompatible with Office 2011?  It seems that Endnote is always behind on schedule or keeping up with the latest versions of software, despite the numerous beta versions prior to official release (of operating systems or software, such as MS Office).

This problem needs to be corrected quickly.  Will probably have to return to Biblioscape or Bookends once again, or perhaps MS Office will come up with a comparable endnote program.  Thanks for dropping the ball once again, Thomson Reuters.

but again: you don’t need a reference software. Apparently Word 2011 works pretty well on its own.
