The only time you run into a WM issue is when you try to ape the OSX singular menubar.<p>As long as you go with the Windows thinking of having the menubar inside the relevant window, your UI will work across just about every WM out there.<p>I really don&#x27;t see why the UI world is so hell bent on moving away from the menubar. That is unless they are stuck up on turning every UI into a touch UI...
