Summary0000998: Broken scrolling with touchpad
Description

chocosaurus reported on IRC that scrolling doesn't work with his touchpad; the scrollbars do move but the pattern position is not actually modified: https://www.youtube.com/watch?v=gOTYRisoExo
It might be the case that we are not handling some scroll message (but I cannot see any WM_* message that would be required to be handled and that is missing).

TagsNo tags attached.
Has the bug occurred in previous versions?yes
Tested code revision (in case you know it)

So far those messages look innocent (different from what my trackpad sends but should still be understood by OpenMPT). We also verified that this was broken pre-1.23 when the MFC workarounds for 32-bit scrollbar positions were added.

Tried it on another touchpad and it also just worked there. Maybe it would be good to know which touchpad driver you use; is it a Synaptics driver?

as far as i can tell i'm just using microsoft default "HID-compliant touch pad" driver - can't see any manufacturer drivers anywhere in device manager - am i checking the right place?

Yeah, that sounds like it's just the default driver then, thanks. Maybe that helps with reproducing the issue, we'll see.
