Cursor-down moves a lot more than 1 or 2 lines

[JustaFoxitUser]

I am using PhantomPDF 9.6.0.25114 on Windows 7. When I read a PDF document and press cursor-down, it scrolls down a lot more than a few lines, but not exactly a full page.

Troubleshooting step #1: When I do the same in another app (e.g., Firefox), it only scrolls down a few lines, as desired.

Troubleshooting step #2: I am using a Toshiba Portege R930 laptop, and the Scroll Lock key is not easy to find. I used the on-screen keyboard to toggle Scroll Lock. This has no impact on the scrolling behaviour in PhantomPDF. To launch the on-screen keyboard, see https://support.microsoft.com/en-us/...b-df46669520e0.

Why is the cursor-down key having such an unusual effect in PhantomPDF? What was the intended purpose of this behaviour? Is there any way to get the more usual behaviour of scrolling a few lines?

It turns out that Arrow Up/Down does not scroll when Select Text is enabled. Instead, it just moves the cursor / insertion point through the text. When the cursor scrolls off the bottom (or top) of the screen, the document pans an entire screenful. It may not be obvious that this is happening unless you notice the presence of the cursor (which can be hard to see, as it is camouflaged by the text).

In order for Arrow Up/Down to pan/scroll a few lines at a time, the Hand tool must be enabled.
