It appears this is part of the deisgn and not a bug, but it's annoying nonetheless and I can't see the benefit of it.
If I scroll 1 notch down or up with the mouse wheel, it does nothing. I have to do 2 mouse wheel notches to make it move 1 notch IOW.
And if I scroll the wheel really slowly, it does nothing.
All it helps is if someone clumsily scrolls 1 notch down/up mistakenly, but it makes people who want to scroll 1 notch up/down have to do 2.
It's just weird :/
Maybe it is a bug.
