Abstract: This invention involves a method and computer memory apparatus for transmitting a portion of one computer screen to another remote computer screen in real time. The user of a transmitting computer might initiate a computer program that allows the user of the transmitting computer to select a portion of the screen to transmit to a user of a receiving computer. The user of the receiving computer then receives a window on the receiving computer's screen, wherein a possibly resized copy of the image on the transmitting computer's screen is displayed. The image might be displayed in real time, and the users of both or one of the transmitting and the receiving computers might be able to modify the content of the image.
