EndNote 8.1 seriously slow on MacOS 10.13

I just returned here after getting a lot of spinning balls in Endnote with each operation (clicking on a reference, marking one as read, etc). Scrolling continues to be impractical, so I have to drag the scrollbar to where I want it. I’ve reported this numerous times, communicated with tech support, sent logs, did various possible fixes, all to no avail.

EndNote 8 is broken. It becomes unusuable slow within minutes of reasonable use. It is NOT an Apple issue, since I don’t see this with anything else on my Mac. In any event, I want to know when Thomson intends to update the app for a possible fix. This is affecting many people, and EndNote has replaced MS Word as my most hated app at this point.

C’mon already-please address this issue.
