Problems with TStringGrid

When I press mouse button on the lowermost cell showing
on a StringGrid, it scrolls up a couple of cells.
I believe it's a natural way to behave, but I'd rather be able
to press the cell without it scrolling and only scroll by using
the vert. scrollbar or by programmatic methods.
Is there a way to solve this?
If not, can I let the grid make another grid scroll by
the same amount?
