The flashing cursor is not visible if I click in text on the right side of the screen/page

I have Windows 10 and use Illustrator CS3 13.0.0.  I create our monthly newsletter in Illustrator.  It's a basic document with some graphics and paragraphs of text.  The header and footer are part of a large graphic with text arranged to the front.  When I have a paragraph of text, I can click among the words and the flashing cursor appears so I know where it is and can arrow over to a spot I want.  HOWEVER, if I click in any text on the right 1/3 of the document (doesn't matter what text), the cursor is not visible.  It's there, as I can start typing or hit Delete/Backspace and letters appear/disappear but I can't see the actual flashing line cursor.  

Even if I click in the left 2/3 of the document and get a visible flashing cursor and then start hitting the right arrow key to go over to the right, when it crosses that "line" the cursor disappears.  I attached two screen shots of what I see.  In the first, I clicked right before the word "paper" in the text.  The cursor was there.  Then I clicked after the word "ballot" and the cursor is not visible.  I know it's there, but not visible.  Not even one quick blink.

Any ideas??

So, one test I just ran (never thought of this until after posting) is to start a brand new document.  It does NOT have this problem in a new document.  Since this is a monthly newsletter I've been doing for years, I just use the previous months' files to start the new one.  This is also the only thing I use Illustrator for so I've never tested it with other files.  Whatever the problem is/was, I guess I'll just start a new newsletter next month and that will correct the problem.  No need to respond to this thread unless you really want to fix my old newsletter files!

Try to copy and paste a whole page into a new doc and see if it goes away.

If not there's some corruption on that page - luckily not enough to screw up your doc but annoying.

If it goes away just repeat for your remaining artboards/pages, at least you won't have to start from scratch.

That worked!

It worked to just paste the content into a new document.  I've always been copying the actual files into the next months' folder so whatever the bug was, it followed me.  All fixed.  Thank you!
