Users do not read dialogs. They. Do. Not. Neither do we developers (admit it). Dialogs are scary things that pop to the user asking to make some kind of selection / decision. Users mostly simply click the little [x] button and hope no further questions would be raised. Regression: do you know what happens in your code if you display a [Yes|No] dialog and the user closes it by clicking on the [x] button?
Among various types of dialogs (and the information inside) you present to the user, be it a warning, error or information, one type actually requires no user input. Such dialogs are those displaying only the OK (or any single) button. It is questionable should you even have a dialog stating something to the user where the only possible user action is to click on the only button (+ the [x]) displayed by the dialog. Anyhow, I’m certain you have (at least I do) lots of those (…,mtInformation, [mbOk], …) scattered around your code.
