You are all absolutely correct, I take back any suggestion I made that this might have been fixed. I just got the useless popup again, saying I'm up to date with 10.5.7. I leave Evernote (Windows) open and minimized on my desktop between uses, and I was NOT using it at the time the popup appeared over the window I was using. Oy! Evernote, no excuses anymore, you need to fix this issue ASAP!
