4D 2004 by default enables the system highlight color in upgraded databases. This applies to new list forms created in the 2004 environment. In addition, if you originally created your list forms in the 2003 environment, the highlight should still remain black after the upgrade to 2004. With an upgraded database, if you prefer to use the black highlight, you can disable the "System Highlight Color" form property. This property is located in the property list for the form.
