--- Comment #5 from Joe Breuer winehq@jmbreuer.net --- Aah, thank you! With 'detach' before AND knowing to prefix the PID with 0x, it works for me.
I strongly suggest to update the docs accordingly, at:
https://gitlab.winehq.org/wine/wine/-/wikis/Wine-Developer%27s-Guide/Debuggi...
Actually - I'll see about updating it with what I had to figure out; since it's a Wiki on gitlab I should be able to...? If not, I'll add another comment here.
