Okay, maybe I understand. So new profiles shows it correctly, but existing do problem, right? Were these existing profile made with old version of mdosbox? What is set in “drive c”? It is not seen on screenshot.
I see there potential bug. You set drive c, but further, path in “main program” does not exists under current context of “drive c” and I incorrectly show content. But I am now on vaccation I cant check sources. Tomorrow I will be by pc. Can it be this situation?
