I forgot that I hooked a tib_keynavigator to my app. This component
handles most of the keyboard events in IBO controls, hence, my
keyboard problems. That said, I remedied the situation by temporarily
disabling tib_keynavigator as follows:

procedure Tfm_jevs.IB_Grid1ColEnter(Sender: TObject);
begin
with tib_grid(sender) do
if col=lastTabCol then
fm_main.IB_KeyNavigator1.GridClasses := ''
else
fm_main.IB_KeyNavigator1.GridClasses := 'TIB_Grid';
end;

Thank you for your replies. I always am learning new things from you.
(Never thought there was an ib_grid.col and lasttabcol :-) )
