After some time of work with my MacBook Pro a saw a strange behavior with the contextual menu “open with”.
Suddenly I had Evernote twice and fourfold and now seven times.
I tried to figure this strange behavior out and found that each copy comes after application update. For example after Opera update this contextual menu will appear one time more. So I think the behavior of a app update is like a new installation. There is a kind of check missing which should check the allready installed path.
