Documents open off-screen

Whenever I open an old Writer document (odt) it is far off to the right of my visible screen and I have to use the horizontal scroll bar to be able to read it.
I must have some setting wrong somewhere, but as a NeoNovice, I have no idea even where to start looking.
Can anyone help?
Thanks and God bless!

Hello,

Unfortunately many who create an account here to ask a question never bother to try and comprehend how the site works. When you have signed in you are on the main page. On that page, there, in the right hand column, is a section called Resources. Please take just a minute or two to read How to use the Ask site. It’s not all encompassing but will provide basic information to ask a bit better question than you have.

There are also a few other links at the bottom of the page - FAQ & Help which are often overlooked and contain other information.
