These options do not appear in my Evernote preferences window. The only place I find this option is if I right click on the app icon, where it lets me I click the option "open at login." This only works temporarily for about 3-4 startups after doing this, then seems to automatically reset again. It's getting real old.
I can get evernote to not open at start up for only one to two start-up sessions, by going to BOTH the startup preferences and the evernote preferences and unchecking startup choices/removing it form the start up list. But after 1 - 2 startups of my mac, it reappears at start up. Very, very annoying...
