Use the options on the Errors tab to set preferences for the display of error messages.

The default fonts for message text and data fields are shown in each of the font message boxes. To open the Windows Font dialog to select font attributes, click the command buttons for text or fields. To modify the font for text messages, click Text. To modify the font for data fields noted in message text, click Field.
Informational messages are not critical; for example, messages that ask whether information should be saved when a dialog is closed.
Warning messages indicate serious, but not critical conditions. A warning message does not interrupt an action, but may indicate that you should reevaluate the current action.
Error messages indicate critical conditions and interrupt the current action. A problem presented in an error message must be addressed before the attempted action can proceed. Error messages can appear in pop-up dialogs, but usually display in the message bar at the bottom of a dialog.
Specify the maximum number of lines (3 to 9) to display in the message bar for any type of message.
Select this check box to hide the message bar when there are no informational, warning, or error messages to display. If you clear this check box, the message bar appears at the bottom of each editor or dialog at all times.
