Anyone else using a gesture Chrome extension like CrxMouse, where you right-click and drag? This is the first issue I've experienced and it's exclusive to the Evernote Web editor (Beta v6.9.1 for me), so I'm assuming this is an Evernote problem.
When I right-click in the Editor everything works as normal. When I make a selection such as "Paste" or click out of the context menu so that it closes, all good. But as soon as the cursor leaves the editor frame, my gesture extension gets triggered yet I'm no longer holding right-click. I think Evernote is blocking a mouse button up event or something.
