QuoteYour original problem was with Wine 10.0. Is this still a problem on FreeBSD with latest OpenMPT 1.32 or 1.33?Yes, at least with 1.32.
QuoteI can also confirm, that wine-staging 10.12 fixes the integration issueI'll try it when 10.12 becomes available for FreeBSD, the latest build is currently 10.10.
