In certain applications, it is desirable to prevent a popup window from being displayed. KioWare can easily be configured to prevent popup windows. When a popup is blocked, an optional dialog box can be displayed to the user with a custom message.

Furthermore, to prevent runaway popups from crashing your application, KioWare can control how many popups can be displayed, and how many levels of popups can be displayed (ie; how many parent/child generations).
