Hi, Sorry, I accidently to not post to the list my last message. I reported the output of xprop on the vlc fullscreen window: _MOTIF_WM_HINTS(_MOTIF_WM_HINTS) = 0x2, 0x25aef1eb, 0x0, 0x46dcdf90, 0x0 WM_STATE(WM_STATE): window state: Normal icon window: 0x0 WM_PROTOCOLS(ATOM): protocols WM_DELETE_WINDOW WM_NAME(STRING) = "VLC (XVideo output)" So no WM_CLASS :(.

Try this in your manageHook:

This is my manageHook: floatAll = composeAll . map (\s -> className =? s --> doFloat) myManageHook = floatAll ["Gimp", "Wine", "Vlc", "MPlayer", "VLC (XVideo output)"] <+> manageDocks <+> (isFullscreen --> doFullFloat) <+> (isDialog --> doCenterFloat) So I alrady do "isFullscreen" in it, no help :(.
