my skype is showing this function but its not working i dont know how to define it but the screen share option is in dull colour i cant access it i dont know you get point or not ?
If you have not yet updated your Skype to the latest 5.9 version, then what you are seeing is most likely due to a bug in the previous 5.8 version, where screen sharing was disabled when the contact was in “Invisible” state.
In recent versions screen sharing with webcam still running is only supported with a Premium subscription. If you don't have Premium, turn your webcam off before trying to share your screen. Then turn webcam back on when you stop sharing.
