I like to tune CW and Data using the mouse wheel, at times. In my WriteLog.ini file I have entered Mouse_Wheel_Hz=3, but I get 30Hz per wheel detent. If I change the ini to =30, I get 300 Hz per detent. I cannot get 3 Hz per detent by using =0.3--in fact, it does nothing. Anyone else seeing this? A head check may be in order. 73, Steve, K4FJ
