Find Full Text feature doesn't work with Endnote x8

Thanks Leanne; I had no idea that there would be some kind of message notification about the status. That was not intuitive at all for me. I was expecting some kind of feedback notification to be displayed along the top of software window where the other messages appear. 

Well, at least I now know that it’s not finding a match, but I’m not any closer to figuring out why. One librarian suspected the DOI might be an issue, but I’ve tried other citations with complete DOI and it didn’t work for those either. Tried the same citation in ReadCube and it found the full text. :confounded:
