I too automatically accepted the udate (I am using Windows 7), but the result is disastrous. The first search after opening Endnote functions as expected; but I then found that a second search for a different author returned no results.After some frustrating looking, it seems that this happens because the option in the search query panel is set to “Search Whole Group” (effectively = Search showing references), and there is no longer an option for “Search Whole Library”.
The problem can only be circumvented by re-launcing Endnote, or by selecting References > Show all references prior to each search query. As I am currently checking the references in a 1000 page manuscript, you can imagine how this is driving me mad. Please provide a solution, or tell me how to revert to the old version of X7.
