This is surely extraordinarily easy, but I can't find it. I recently installed a new Windows environment, installed TextPad, and in the new environment the cursor, i.e. highlighted line, doesn't follow when doing a Page down or page up. That is, if I press page down, then the down arrow, I'm returned to the previous page, since that's where the cursor stayed when I pressed the Page Down.
I've tried to compare my Preferences in the new environment against the old one, and I'm obviously missing the setting. What is it that will get the cursor to follow on Page down/up? (It follows on Ctrl-Home/End without a problem).
