Hi Ken,
The sequence end time was reached during “delay between” exposures. The normal end of sequence message box was displayed but it hung at the 30 second countdown: Clicking on it caused the normal end of sequence actions except gear connections were left green for all but the camera. Clicking on them to close the connections gave an error that the device could not start so they were actually disconnected and just the display is incorrect (obviously no biggie). The switches turned off like they should. The “Disconnect all equipment at sequence end” box was checked.
