APPLICATION SHARING

A method, apparatus and computer program for application sharing is disclosed. On a local display of a sharer network node, a graphical representation of a virtual area is displayed, and respective graphical representations of a first viewscreen object in the virtual area, a second viewscreen object in the virtual area, a user who is present in the virtual area and operating the sharer network node, and one or more other communicants who are present in the virtual area and respectively operating one or more other network nodes. In a screen layout (506) of windows (510-514) on the local display 508, multiple windows (510-514) are selected that are associated with a first software process based on user input in connection with the first viewscreen object, wherein at least one of the selected windows is at least partially obscured by one or more unselected ones of the windows in the screen layout. A first sequence of successive composite images (524) of the selected windows (510-514) are generated as they are arranged in the screen layout (506) at different respective times but free of obscuration in any area obscured by any of the unselected ones of the windows (510-514) in the screen layout (506). The first sequence of composite images (524) is transmitted from the sharer network node (12) to a particular one of the one or more other network nodes (14) in connection with the first viewscreen object. During transmission, a second sequence of successive composite images of windows associated with a second software process are communicated between the sharer network node and the particular other network node in connection with the second viewscreen object.
