Web pages are off centre to the right, argh!

This happened before and I've forgotten how I fixed it. Basically when viewing a web page like PH the page has dropped down to the right. I can see the desktop behind it. The email pages are fine and centred correctly. I can't move the page to centralise it but know the fix is simple.

I'm using windows 10. Can anybody tell me what 'clicks' I need to do? Thanks.

Sorted, I think I pressed the windows buttom and the home button. All back to normal, phew.

Windows and Down, more likely?

It is safe to experiment - you can just keep pressing those combinations until it goes back to where it started!

Thanks, at least I have an idea for the next time:-)
