title: Centering OK button within a MessageBox in winforms
body: <p>I am learning C#, and as a part of it I wrote small app that consists of form with two groups of buttons, two buttons each. Button for closing of app is added as well. And everything works ok. Also there is MessageBox, showing that the app is going to be closed. <strong>And here is little problem that bugs me: OK button within that MessageBox is NOT centered horizontally.</strong> I guess there is a method to align that button, but what puzzles me is why it's is not centered by default? As illustration here are screenshots:</p>
