Ross, if you take a look at the code that gets executed when you enable the
button:
procedure TControl.SetEnabled(Value: Boolean);
begin
if FEnabled <> Value then
begin
FEnabled := Value;
Perform(CM_ENABLEDCHANGED, 0, 0);
end;
end;
you see that it only changes the Enabled property value if it has to.
So I would go for option 1 - mainly in the interest of keeping the code
clear. I haven't tested it, but I think the speed difference would be
negligible.

Subject: [DUG]: Speed question
Which of the following statements execuates faster if the button is
already enabled?
1. OKButton.Enabled := True;
2. if OKButton.Enabled = False then OKButton.Enabled := True;
If the answer is 2, does anyone bother doing it that way?
Also, if I'm enabling the button in numerous procedures, is it
better/faster to execute a procedure with just the one line in it?
Cheers,
Ross.
