How to quickly change mouse wheel scroll lines?

[don_AC64]

I have tried this code; it works, but seeing the window appearing and disappearing is not so fine; is there faster way?

Code:

Copy      Help

run "C:\Windows\System32\main.cpl" ",3"
0.1
int w=win("Mouse Properties" "#32770")
Acc a.Find(w "TEXT" "" "class=Edit[]id=105[]value=1" 0x4)
a.SetValue("5")
key Y

I have tried the MouseWheel function, but it seem not to respond adequately when I rotate the mouse wheel too fast with some programs.
