I was running a test and at the end I warmed my camera (ZWO ASI1600) and shut down other applications. I returned to SGP and tried to disconnect all equipment (Crtl-Sh-D) while in Frame and Focus mode (I forgot to Stop it). SGP hung and would not respond, so I had to kill SGP from the Task Manager. SGP eventually did try to put up the exit dialog for saving the sequence, but the dialog did not complete its rendering and was unresponsive.
