This problem started happening to me today. I think it may have also happened once or twice within the past year, but today was bad enough to find this forum and post about it.
Windows 10 Home 64-bit Version 10.0.19041 Build 19041
Chrome Version 87.0.4280.141 (Official Build) (64-bit)
Chrome web 10.6.9-web (225) New Editor
Editing an existing text-only note
I tried turning on Chrome's "Do Not Track" setting without success.
My laptop's touchpad is already turned off.
Switching from "New Editor" to "Classic Editor" seems to have fixed the issue. When I switched, Evernote asked me to take a survey about why I was switching and to inform me that the "Classic Editor" would not be available for much longer.
