I am having a similar problem. I have added the Endnote tools to word 2007 in the Add-in toolbar. I can add references to word documents, but the references show only as text. They do not behave like endnote references in Word 2003 that hightlihgt if you click on them. When trying to format the citation, both endnote and word hang. I have tried uninstalling to no avail. I am running windows XP with Office 2007 sp1 and Endnote X.0.2.
