On the General page, set values for Use Extended Attributes or Read Only as follows:

Preference	What you do	Effect
Use Extended Attributes	Clear the check box	Does not create the DataWindow Designer system tables if they do not exist. Instead, the painter uses the appropriate default values for extended attributes (such as headers, labels, and text color). If the DataWindow Designer system tables already exist, DataWindow Designer does not use them when you create a new DataWindow object.
Read Only	Select the check box	If the DataWindow Designer system tables already exist, DataWindow Designer uses them when you create a new DataWindow object, but does not update them. You cannot modify (update) information in the system tables or any other database tables in the DataWindow painter when the Read Only check box is selected.
