To work in the background mode initialize processing and, when a small dialog box showing the progress bar appears on the screen, click the Minimize button situated in the upper right corner of the dialog - DART XP Pro will be minimized allowing you to use other applications. The percentage processed will update the title of the DART icon situated on the Windows task bar. This should help you keep an eye on DART’s progress while doing other jobs. You should be aware that when operated in the background processing mode DART XP Pro may work much slower than usually as it has to share the processor’s time with other applications.
