If the Errors In Dialogs box is checked, LINGO will display error messages issued by the solver in a modal dialog box. This dialog box must be cleared before LINGO proceeds with any other operation. In some instances, you may have LINGO embedded in other applications, where it may not be desirable, or possible, to have users clearing error dialogs. By unchecking this option, LINGO will route the solver's error messages to the command window, where they will be displayed, and no user intervention will be required to clear the messages.

The default is for solver errors to be displayed in dialog boxes.
