Sadly that didn't work. The specific problem I'm having is when I create a new note in Evernote (or receive a message in Line, a messaging app), the taskbar pops up.
(Everything is off under notifications except for Skype and Focus Assist, which are grayed out.)
When Evernote is in focus --when it looms large on my screen-- and I create a note using a hotkey, the taskbar stays silent. But when, for example, I'm here, in Chrome and press a hotkey, the taskbar pops up. The taskbar stays popped up until I click on the flashing Evernote bubble on the taskbar.
