I can see you - can you see me?

Trying out the newly installed webcam for video calls and conferencing in the office today. Fellow Blipper and colleague Lesley, who was in an office about 15 miles away, and I eventually managed to get to grips with it after a few problems - I could hear her, but not see her, she could see me but not hear me etc, etc.
Technology is a wonderful thing - once you get your brain into gear!
