Summary0002287: 2D panning (using adjust) does not work properly if the h-scroll bar is tiny.
DescriptionNormally RISC OS lets you hold adjust on either scrollbar and pan about an image in 2D. If you shrink NetSurf's horizontal scrollbar too much, adjust-scrolling stops working horizontally.
Steps To ReproduceFind a giant image, or zoom in on a smaller one.
Drag the h-scroll slider most of the way right so that most of Netsurf's lower bar displays URL info, and the h-scroll bar only displays a couple of arrows.
Grow it a little bit so that the scroll-bar just reappears.
Adjust click on the tiny h-scroll, and you can only scroll up and down
Adjust-click on the normal-sized v-scroll, same applies.
Resize the-scroll bar so that some empty scrollbar is visible.
2D-panning comes back again.

This affects me because I have the URL info bar open as wide as possible so I can read extra-long URLs.
Additional InformationThis Imgur image is large enough to see the effect.
I use 150% zoom on a 1680x1050 desktop.
