Organ stopped loading automatically

Until recently, whichever organ I had loaded when quitting Hauptwerk would load automatically when I reopened Hauptwerk. For some reason this behaviour has changed, and now when I open Hauptwerk nothing loads, and I have to manually load the organ every time. I looked through all the menus and could not find anything about this. I looked in the manual and couldn't find anything about this. Normally something basic like this would be a setting in the Preferences window, but Hauptwerk has no standard Preferences window. So I am asking for help. Thank you.

The option is in place....
[General Settings] / [General Preferences] / [Main] / set "Load organ when Hauptwerk starts" to "Load last-used organ", then [OK]
Hope that helps.

Yes, that's exactly what I was looking for and couldn't find. Thanks
