When I scroll a list for example in Total Commander's Synchronize Dirs, or in a text file with its Lister, scrolling is very slow, if I do multiple scrolls at once.
The problem is that if the lines I want to skip are many, I do many scrolls on the wheel. I expect it to scroll much more at once! But Windows handles this really differently, and if you ask me in a buggy way, because multiple scroll slows it down more than if I would have done separate scrolls (or at least it feels like it). In particular the actual looks feel buggy, too.
I've tried to set the scroll speed according to this: Change mouse settings basically says:
Control Panel → Mouse → Wheel tab; set your stuff.
I've set it to screen and later to 10 and noticed that the scrolling is still slow. I suspect it's the animation.
