Some window managers implement the starts on desk functionality by inspecting WM_COMMAND and then parsing the command line. In this case that probably means that the invisible (AppShell) window gets mapped on the correct desk, but the first frame (which doesn't have WM_COMMAND any more) is not. Basically this feature is broken-as-designed. Jan P.S. One could put WM_COMMAND on the first frame as it is mapped an then remove it, but frankly I think there are better ways to implement the functionality. (i.e. give the initial frame a special name and then tell the window manager to map that frame on the correct desk).
