Problems with Logitech webcam

[mikethebook]

I really don't know what forum this should be under but I'll try here. I regularly use Skype with a Logitech webcam and have no problems except when Skyping one particular friend when my webcam doesn't work. I can see it trying to open but it never does. And I'm the only person my friend Skypes with who has this video problem. I tried contacting him on VSee but once again my video wouldn't open. He is on a PC so I couldn't use Facetime but when I tried opening it, my picture didn't come up but maybe it doesn't until you make a connection. After a frustrating time Skyping yesterday I tried my wife today and the camera worked fine. So what is the problem with Skyping this one particular person? He is in the USA and I'm in the UK but I Skype regularly with others in the USA. Any thoughts please?
