Idle Time-out On Messages
This is where you can specify that the Idle Time-out Time and Actions properties must work even if message boxes are displayed.
Normally, an application will stop while a message box is displayed. If you set this property to True, and a time-out occurs while a message box is displayed, the application will revive. It will resume the original activity, and once that has finished, the actions specified as the Idle Time-Out Actions will be executed. These actions are specified using the Idle Time-Out Actions property. The message boxes will be left on the screen for the user to clear later.
Note that question messages will be cleared automatically; they will be treated as if the user canceled the message.
The Idle Time-out On Messages property is an application-level property.
