--- Comment #4 from Olivier F. R. Dierick o.dierick@piezo-forte.be --- Hello,
Probably a dupe of bug 42497 or bug 46314.
Current rekordbox from the website is 6.4.1.
As a quick test, searching for the string 'wine_get_version' matches 3 files, including the main executable 'rekordbox.exe'.
I don't know if it relates to UpdateLayeredWindow() or another wine-aware broken thing, though, so it needs deeper testing.
Regards.
