(No, not a Scottish island )

Disclaimer: This has been happening to a friend for a couple of weeks

He has asked me to help resolve it.

The system is [the latest] Win 10 and Skype on a Lenovo laptop of modest means.

Previously on Skype he was having no problems.

So we did all the usual checks:
Skype and Windows permissions to use camera;
check camera works in another app (Camera app in Win 10);
camera is NOT being used by another app/no other process running;
check bandwidth/line speed (blazingly fast!)

The answer: YES to all the above.

Checked the Skype help forums: do everything you have already done

I have got nothing left to do/check that I can think of/have read about.

Can anybody here add to this tale of woe/provide the magic bullet?

My suggestion to the user - talk to your contacts by installing and using the Skype
app on your phone (as I do as an adjunct to the computer app)
- or, sail over the sea to Skye - ie, leave the "p" off
