Sudden Black Border

[RJK--Editor 7]

Suddenly, all my notes have a broad black border on right and bottom (see attached). Every old note has it. When I create a new note, it has it. The borders remain if I reduce or expand the note size. I never use templates. I've closed and reopened the program several times. I simplified and eliminated formatting. Nothing changes this. I've made no other recent Windows changes and no other programs are behaving oddly. Any thoughts on getting rid of this?

Hi.  Not sure I've ever seen this.. have you tried restarting your device?

I just got a solution from the Evernote help desk. They suggested a nd forced close (control alt delete).  That seemed to do it!
