@SearchingDataOnly, did you test the new update ?

As further information.. the MS(H)FlexGrid is also lame/lazy (1 liner scroll only) on the "up" and "left" "capture mouse move" scroll.
So the VBFlexGrid is in this regard now better as to take the distance and calculate actual number of lines to scroll, like in the "down" and "right" scroll which is done naturally due to MouseRow/Col.
