I have an old Combi-Pal (model MXY 02-00B, firmware 2.2.7) mounted on a 7890A with an 5975C controlled by Chemstation E.02.00.493.

I would like to run the Combi-Pal in stand-alone mode. To do this, I need to set the Auto Prep Run to ON in the configuration menu on the 7890. When I try this, Chemstation turns it off whenever I load a method. Chemstation also won't load the GC setpoints until I reboot the GC. Is this a known bug or am I doing something wrong?
