A friend is running an Acer laptop (dual core 1.8GHz with 3Gb RAM), Windows 7 (64-bit), Word 2007 and EndNote X2. The laptop works at a reasonable speed doing any other tasks until Word AND EndNote are opened together. It then crawls along and takes minutes for any keyboard or mouse input to action. CPU is only trickling along at a few percent. Word on its own is fine however big the documents are. A recent upgrade was made to antivirus AVG 2011 (free) version.
Machine is clean of viruses and malicious software, and no errors noted. Any clues as to how to solve this one please?
This is likely due to the number of styles installed by default, and the way Endnote handles them. See this thread. This was somewhat fixed in X3 and X4 which only loads a subset of the styles (and connections, and filters). – but even then, not necessarily the subset you wanted!
Have you updated Endnote to the latest patch? The original endnote X3 does this when run on 64-bit windows 7, but they released a point upgrade which fixed the problem.
