On Mac OSX 10.11 (El Capitan), EndNote 7.5 automatically starts whenever I start Word 2011, and even when I simply open a new Word document. Endnote 7.0 worked fine. “Open Endnote when starting Word” is unchecked in CWYW preferences, so that’s not the issue. Endnote behaves fine with Word 2016, so the problem is limited to Word 2011. Anyone else seeing this? Much appreciated!
Yes I believe that this is a bug that has been reported - see this thread.
