On my new iMac, I could be looking at a web page/article then suddenly it disappears with no action on my part. It switches to another screen suddenly. I have noticed moments before this happens, a broad grey arrow appears for a fraction on the extreme left edge of my screen. Very annoying.

Possibly related, when I open FaceBook, I look at the second article at it too suddenly disappears. The annoying part is it usually looks very interesting then poof! it disappears. This only happens in FaceBook.

Can anybody advise how to stop this happening.
