I have some pngs for you, can I just drop them here? Let’s see. Infopedia in full after hitting the scroll down button until the Sensors topic is highlighted. This is the first issue: scroll down button should move the DOCUMENT UP not the highlight down.
Next is a snippet at the bottom after hitting scroll down button ONE time, observe Ship Controls is highlighted and the text on the right has changed to match, but it is partly obscured.
Now hit it once more:
Whatever topic follows Ship Controls is (presumably) highlighted as the text on the right has changed. Hit the button a couple more times,
The selected topic is now … Torpedos?
Also I observe the problem @Antz reports, when you scroll-down in the right (text) panel, you can’t go back up, and now EVERY topic you select has been scrolled-down.
