In upcoming versions can we do a bit better than popping a box that says “Endnote X7 Unknown Error”. May I humbly suggest that if Endnote and MS Word don’t know what kind of an error it is, the poor user has no way of knowing what is going on. Usually I find that this error message can simply be ignored and that all is well, but when a document runs more than 100 pages, and has 75+ citation links how precisely would I track down a problem if one actually did exist with only this unhelpful message to work with?
