Web Clipper launches an old version of Evernote App (5.0)

[MJG 16]

If I use web clipper in Safari on any of my Macs I am getting a bizarre behavior.  

Once the clip is done, you are offered the options of opening the newly created note in the web version or the desktop version of EN.  (I have noticed that Web Clipper is a little unreliable unless you immediately open the note in Evernote on the same device that you used to create it.)

If I choose to  open the desktop app, an old version of the app (one that isn't even installed on my computer) launches (Version 5.0), starts the slow and lengthy process of loading all my notes (several thousand of them) and freezing out any further activity until the process is either finished or I force quit the old Evernote.

Evernote, Safari, Web Clipper and MacOS are all fully updated on all my computers.

Searched the discussion boards and didn't see anything like this. I was wondering if anyone else is experiencing it?
