A local computer 132 is connected to a remote computer 136 over a network for collaborative processing, whereby changes to the screen of the local computer are to be reflected on the screen of the remote computer. A hook routine 110 is used to intercept requests to update the screen of the local computer, and the area of the screen to be updated is determined from the request. Another routine then obtains the bit map for the area of the screen which has been updated, and only this bit map is transmitted to the remote computer, rather than one corresponding to the whole screen.
