I have not noticed this. Is there anything peculiar about the
situation, or is it happening with all your grids?

I suspect we may need more information such as the version of IBO and
Delphi that you are using. Perhaps you could post the Grid definition
from your DFM to show us what settings are being used. If we cant
reproduce it easily we may need you to write a small demonstration of
the problem.
