Naomi,

You are just too darned picky *bg*

>I'm afraid that setting status bar of all controls is not enough :( I have a form where I set every single control to have a statusbar. Still when I press the upper right close button of the form, I see this Opt. thing.

I don't know (and can't check now) if there is any event you can bind to and either tweak the SET NOTIFY on/off as necessary to get rid of the message.
