Is the Jump Map supposed to persist? Intuitively, one would think that it should. There is plenty of space for it within the window even.
When I open it, I click on the small map to go to the section I want, but the Jump Map small window immediately closes, which means I have to keep opening it. Very user-unfriendly.
Also, it's very bizarre, but while I'm in the forum editing this message, I use my arrow keys and the map in the background scrolls - so apparently it doesn't see what window has 'focus'. Could be a problem for people multitasking (for example, in chat rooms).
In case it's relevant, I'm on Windows 10.
--Just wanted to say that I know it's a pain to get flooded with all sorts of bug reports, but I've been in your position. I'd rather hear about this kind of thing than to be unaware.
