After working for hours ... (by the way I forget to tell that
another difference between the control grid besides the number of
records is that the 2 control grid is on the same form where the
ib_query and datasource is while the 3rd and slow control grid is on
the other form.) After I put the 3rd control gird into the same form
where the ib_query and datasource is ... then everything is fast
again ... I wonder how is having control on the different form
affects?

I try to put the control grid back to the other form with the
ib_query and datasource it needs.... but the ib_query.keysource is
on the other form, still very slow.

can somebody give me some notes on this one?

thanks
