Joe's explanation hits the nail right on the head of the hammer. I too am not sure what you mean by Tab Out ? Unless you mean you are using the Alt/Tab Keys in Windows to go from one app to the other. If that is the case then that would still be recorded and as Joe stated there is no way to prevent that showing up in the video while recording and would take some editing and timing when recording to accomplish that task. Hope this helps and maybe let us know what you mean by Tab Out would help. Have a great day/night and thanks for posting.
