mouseScroll speed

Just bought a new Logitech M100 wired mouse…
and the scrolling was rather slow, and adjusting it in SysPref made little difference

So I adjusted the System Plist and change

BUT scrolling DOWN is painfully slow… any idea?

if I switch the “Natural Direction”, then scroll down is OK and scroll UP is too slow

Sorry to point to the obvious, but it looks like the mouse is faulty or incompatible (if that’s possible).

Edit: did you install any Logitech software? You can try SteerMouse to see if that helps.

I have been using Logitech mice for years…previously a M110 which is no longer available… this is an M100… nothing fancy

And no installed special software…

Oh… and it is 3 different mice tried on 2 different computers
