So I had Skype in Leopard and it worked fine. However, ever since upgrading to SL, whenever I try to launch a video chat or go to the video prefs in Skype, it says the camera is in use by another application. I have the latest version of Skype installed, and I have uninstalled and re-installed it several times. I have repaired permissions and still nothing works. I have quit every application and launched it and it still says this. Anyone have any suggestions?
