 *  ntf22Aug97: Changed Component::GetItemValue to be more robust.
 *	awm02Oct97: Added a check to see whether the global _theConfigManager already existed before
 *				setting it equal to the config manager being created.  This is to support multiple
 *				config managers within the application
 *				Took out a line which set the global "_theConfigManager" to NULL in the destructor
 *				of the IniConfigManager.  This will have to be done manually when the config manager
 *				is destroyed in the main application.
