I don't know how it happened, but my Word has now those border lines on
each
corner of a document page. I tried several ways to undo that, even
restarted
my PC, but with no luck. Every new document and old documents get that
when
I open them. In attach, there's a small picture of this behaviour. Does
anybody know how to remove those?

Regards!
