--- Comment #3 from Johannes wine@sagagames.de --- OpenMPT is affected by this issue even in the current Wine 4.7.
To reproduce, download OpenMPT from https://openmpt.org/
Create a new file, go to the "Samples" tab, and drag one of the *.flac files coming with the program into the black area on that tab (which has WS_EX_ACCEPTFILES set). The FLAC sample is expected to be loaded into the sample editor, you should see its waveform in the black area. But instead the top-level window of OpenMPT receives the file, which tells OpenMPT to load this file as a module instead, and you will get a message that it was unable to load the file.
If it's any help for debugging, I'm the OpenMPT developer.
