I don't know if you can help, Miscrosoft is useless so have given up on them. For some days now I've been getting a grey box with red printing appearing repeatedly on my screen, right in the centre. Try as I might I cannot get it to stop. It could have something to do with videos as today it started appearing after I looked at a video on Twitter. I have included a photo of the box Weirdly, I can't take a screen shot of it - it comes up blank and also, the cursor disappears behind the box and is invisible.
If you can't help could you point me to where I might get help please?
Thank you. Jenny
