The desktop defines a default shadow thickness of one pixel for the components in application windows, such as button shadows and focus highlight. Motif 1.2 applications use this resource value; other applications may not obtain this resource value and therefore will appear different on the display.
To set the shadow thickness to one pixel for non-Motif 1.2 applications:
Log in as root.
Create the /etc/dt/config/language/sys.resources file.
Specify the application-specific resource in /etc/dt/config/language/sys.resources as follows:
application_class_name*XmCascadeButton*shadowThickness: 1
