Changing MenuItem at RunTime

MenuItem.caption := 'NewCaption';

The above line works fine.  You CAN change the caption at runtime.  I just tested this to verify.

I suggest that you delete all temp files, and do a rebuild.  That will sometimes fix strange errors.

Edited text of question

I know I cant or else I wouldnt ask the
question. Maybe in Delphi 2 and above you can
but in Delphi 1 you cant.

sleach's suggestion seems to work fine for me in D1, I just created a new form with a TMainMenu, inserted the "File" menu template, then added a button to the form and put this as the OnClick event handler:

procedure TForm1.Button1Click(Sender: TObject);
begin
  New1.Caption := 'Newer' ;
end;

I run the program, the "File" menu shows normally with "New" as the first item, I click the button, now the first item has become "Newer" just as would be expected.  Is this not what you're referring to when you ask "How do you change a menuItem at Runtime?"  If it is and still isn't working, can you maybe post some source code so we can see more precisely how you're doing this?

I found the problem was that I was changing the caption
is tne OnClick event of the CLOSEBUTTON the event for
some reason did not actually occur, and I needed to change the
caption from within the unit I had the menu object in.
