Reporting4Act! has the ability to report on special database structures created through the Durkin Toolkit (this feature is available at the Ultimate license level). Processing these database structures can take some time during the database connection process, so if you will not be reporting on these items, it's possible to disable this detection process entirely. This is done by adding a DetectDurkinExtensions=No item to the [Options] section of data.ini.
