The MessageBox is used, because it can be handled completely
by the widgetset and therefore works even if the heap got corrupted.

It is a matter of priority. Show some information to help fixing the
bug, or help the user to ignore the bug.

We could:
Add a flag to Application so that the programmer can decide what to
show (MessageBox/QuestionDlg).
And/Or: add an event to let the programmer show its own dialog.
