Coordinating mouse wheel and scroll bar in TStringGrid

When I SCROLL to a certain position in a StringGrid with the vertical scroll bar and THEN use the mouse wheel to go further, the current position always goes back to where the last scroll operation started (plus one for the mouse wheel operation).
E.g. When I start the TopRow is 0
Now I click into the scrollbar which moves the TopRow to last visible row, let's say 10
Now I turn the mouse wheel down one position -> the TopRow becomes 0 + 1 = 1

Any idea of coordinating both scroll operations?
