Skype 5.5.0.2340 --- iSight not working
I recently installed the latest version of Skype on my iMac and get only a black box in the "audio/video" preferences menu within the program. I can make calls and see the other person, but they can not see me. When I click on "video" on the bottom portion of the window, it says "your video is turned off".
The built-in iSight cam works fine in iChat, Photobooth and FaceTime. And all of that software has been turned off and closed.
I've read through every discussion in community and the Skype communities and nothing has worked. Please help.
