When trying to capture a text consisting of about 7 pages with FastStone Capture to be able to print it, the scrolling automatically stops after only 3 or 4 pages are scrolled. Why?

Could it be that the red border that pops up when I hit the automatic scroll button is limiting the scrolling to only the first 3 pages? Have tried in vain to get rid of the red border.

I save to Editor before I start scrolling.

I am on windows 10.

Many thanks in advance to any help you can give me.
