I am having the same problem except that I have to sign in several times an hour. If I open a browser tab in a new window, then save to evernote, I will have to sign in again. If I click on one of the "Related Notes" on the "Clipped" message, then the note will try to open in a new browser window and will display nothing. At this point if I open another 'tab' in the same browser 'window', go to evernote and login, then I can refresh and see the note. However, when I return to the browser window I started from, then I am logged out of evernote. There are many variations, but the gist is that almost every time I use the web clipper, I must sign-in over and over again. Nothing to do with clearing cache or cookies or logging out, not at all. Simply clip a few times, then login again. I am using Safari Version 6.0.5 (8536.30.1) on OS 8.0.4 Mountain Lion on a MacBook Pro. And I am using the Evernote Web Clipper. I don't know how to view the script it is running because it is on the 'toolbar' not on the 'bookmarks' bar. I have a premium evernote account. Is there a workaround for this? Also, this is a new bug. I cannot pinpoint exactly when it started, but sometime within the last few weeks. And, fyi, this is horribly, maddeningly frustrating. Especially because it is a new bug.
