Please help - currently running Mac version 10.10.5 with dual monitors. When open, Evernotes window now defaults to fullscreen only without an option to minimize (Command +M doesn't help) and with the menu auto-hidden. I I've been a prolific Evernotes user since 2012 but cannot multitask and access notes at a moment's notice when clients call as I've been doing forever. I really don't want to switch to another notes platform as I have tons of content stored and organized already. SUGGESTIONS PLEASE!
