if your app ever pops up a dialogue box that wasn't specifically created by an input event with the clear implication of "create a dialogue box", it is broken.
It doesn't matter if there's an error. A dialogue box is the wrong way to indicate errors.

I spent most of my time on windows 95 and 98 actually booted into their semi-protected-mode DOS, in part because of dialogue boxes.
