I am the original poster in this thread. I bought a new computer recently and installed Evernote 11 and I can say that in two weeks of use, I have had no issues with the new version. On my Windows 10 laptop, all seems to be good also.
I can see all my notes in the left column, but clicking on a note does nothing - the note does not open. On the web, I can see the note thumbnail and the full note, but not on the desktop.
