To clarify -- the problem is with GLOBAL KEYBOARD SHORTCUT. So with Evernote 10 installed you cannot use the Windows system! Not just Evernote. People cannot use their Windows. This is because every time you try to write "ś" in any application, Evernote pop-up appears
Evernote working in background is hijacking basic keyboard usage. This is definitely true for Polish speakers. Possibly also for other languages like Finnish, Czech, Slovak etc (all those having diacritics with s).
