--- Comment #6 from Jerome Leclanche jerome@leclan.ch --- FWIW yes, it detects wine and disables the menu by default. There is a MPQEditor.ini config to reenableit but I can't find it right now - it might have been renamed to "MainMenuType"...
Hard to tell but anyway¸ not worth the trouble I think.
