I just upraded to X4 (on a Mac 10.6 with Office 2011). I notice a new behavior: it now makes a new group with the references from the current document. That’s fine; but the bad part is that when I find and then insert a bunch of references into the document, the Endnote window switches into a view (group, on the left frame) where it shows me the group of refs from that document and I have to click back to “search results” to go back to the group where I was - an extra click. How to disable this?!?
