"I can imagine tha you may get users to read by providing good button labels. If the button label is always "OK" then yes, noone will read anything and just click away. If your button labels provide the action or in Y/N dialogs something like "Yes, do it anyway" you probably have a better chance of people reading the text above (user thinks: "anyway? wait... do what... why anyway... what's in the whole dialog text...")"
That's right! In a relaxed situation a user will never read those pop up windows. But if he/she sees something alarming - then they concentrate their attention on dialogue box. In big [custom software development company][1]custom software development company they have QA depts to test not only the performance of a program but user behaviour, as well.
