Here is some code Roland Stowasser wrote for me. It assumes right click but you
might be able to use when moving the mouse with some adjustments.

procedure MenuEditList_Mouse (integer self, integer event, sequence params)
--Roland right click

    integer index, state
    atom bool,height,topindex,indexoffset
     
    if params[1] = RightDown then
--you would use MouseMove above instead of RightDown or LeftDoubleClick
        
            height=sendMessage(Combo2,LB_GETITEMHEIGHT,0,0)
            topindex=sendMessage(Combo2,LB_GETTOPINDEX,0,0)
            indexoffset=floor(params[3]/height)
            index=indexoffset+topindex

            bool=sendMessage(Combo2,LB_SETCURSEL,index,0)
            index+=1
            if index>getCount(Combo2) then
                index=0
            end if
    end if        

Hope this helps; sorry I did not have time to test the code.
