InoWhile Zowie wheels aren't that good in general the problem with slow wheel turns not registering is due to the optical wheel encoders, like Bucake already said. It's inherent in the design. That being said, you have to scroll extremely slow for that effect to come into play. Is this just theoretical or do you actually scroll that slow?
I don't normally scroll that slow but I did today and was startled and thought that something inside of the mouse was broken but it looks like its just the optical encoder.
It's a shame cause I have an old deathadder lying around but i dont like the shape of it as much as the zowie, wish I could just morph the two into one and take the good scroll wheel from the da and put it on the za11. Thanks for the help
