I launched this program two times, the first launch have been successful. Then I closed it and relaunched but nothing happened. Here it is the result of the second launch in the terminal (hope to have done it right): AL lib: ALc.c:1808: alcCloseDevice(): destroying 1 Context(s) fixme:dwmapi:DwmSetWindowAttribute (0x50162, 2, 0x32d54c, 4) stub fixme:dwmapi:DwmSetWindowAttribute (0x50162, 3, 0x32d550, 4) stub fixme:dwmapi:DwmSetWindowAttribute (0x50162, 4, 0x32d554, 4) stub fixme:process:GetLogicalProcessorInformation ((nil),0x440f578): stub fixme:process:GetLogicalProcessorInformation (0x764cc00,0x440f578): stub err:ole:RevokeDragDrop invalid hwnd (nil) err:ole:RevokeDragDrop invalid hwnd 0x2014e fixme:win:LockWindowUpdate (0x6002e), partial stub! fixme:win:LockWindowUpdate ((nil)), partial stub! fixme:win:EnumDisplayDevicesW ((null),0,0x440f618,0x00000000), stub! fixme:win:EnumDisplayDevicesW ((null),0,0x440ec30,0x00000000), stub! fixme:win:EnumDisplayDevicesW ((null),0,0x440e634,0x00000000), stub! fixme:win:EnumDisplayDevicesW ((null),0,0x440e738,0x00000000), stub! fixme:devenum:DEVENUM_ICreateDevEnum_CreateClassEnumerator Category {33d9a760-90c8-11d0-bd43-00a0c911ce86} not found fixme:devenum:DEVENUM_ICreateDevEnum_CreateClassEnumerator Category {33d9a761-90c8-11d0-bd43-00a0c911ce86} not found fixme:mixer:ALSA_MixerInit No master control found on HDA NVidia, disabling mixer fixme:mixer:ALSA_MixerInit No master control found on C-Media USB Headphone Set , disabling mixer fixme:mixer:ALSA_MixerInit No master control found on USB Video Camera, disabling mixer err:alsa:ALSA_CheckSetVolume Could not find 'PCM Playback Volume' element err:alsa:ALSA_CheckSetVolume Could not find 'PCM Playback Volume' element err:alsa:ALSA_CheckSetVolume Could not find 'PCM Playback Volume' element fixme:devenum:DEVENUM_ICreateDevEnum_CreateClassEnumerator Category {cc7bfb41-f175-11d1-a392-00e0291f3959} not found fixme:devenum:DEVENUM_ICreateDevEnum_CreateClassEnumerator Category {cc7bfb46-f175-11d1-a392-00e0291f3959} not found
