Using Evernote 10.57.6-mac-ddl-public (4112), "Paste into Evernote" via Ctrl-Cmd-V does not work. I also have a computer with Evernote 7.14, and it continues to work fine there.
I changed the global shortcut from Ctrl-Cmd-V to Ctrl-Cmd-P. Now it seems to work. But not always. It sometimes works, but sometimes it requires Evernote to be in the foreground.
This implies there is a conflict in shortcut key assignments. However I have always used Ctrl-Cmd-V, so there should be no other conflicting assignment. Further, I sometimes use a tool called Cheatsheet.app to show what key assignments are available. While using that with Evernote in the foreground, it shows no assignment for Ctrl-Cmd-V (before I changed it).
So I am thinking that the Evernote shortcut keys are messed up.
