Message Manager Lite is a fun practical joke program that lets you display fake error messages and other types of dialog boxes. To use Message Manager, simply type in your message text, choose a graphic to display (e.g. error message, warning message, informational message, or confirmation message), and select up to nine buttons (such as Yes, Cancel, Retry, Abort, and Ignore). You can have the fake dialog appear at a preset time, or after a specific number of minutes.
