I have just set up my Skype and in making my first Skype to Skype call, I had good video and audio from my contact, but he could only hear me and receive a "still" video picture. There were no other operations open on my PC. bwhitelover
For no apparent reason the problem has resolved itself, but thanks anyway. Incidentally, I went to "Call menu/call tech. info. and did not understand a word of it.
