Ok, here is the answer from the author of CaPriCe Forever ...
Caprice will check the content of the catalog to find a visible single file with BAS, BIN or no extension.
In that DSK, there are several visible BAS files. Caprice is not able to know which one to launch.
But, there are something to do.
If you open the Files Manager window, and hide the file "MANAGER.BAS".
Now, the autostart should work by launching "BJES.BAS".
I don't know if that's a final solutions or if you can somehow manage to rename MANAGER.BAS, so that only BJES.BAS is left? In this case AUTOSTART would work.
Cheers
