Abstract

Abstract A data processing system having a window based display and a processor executing a plurality of interleaved data processing tasks each having one or more associated display windows, wherein execution of a first task may trigger execution of a second task, characterised in that when execution of said first task triggers execution of said second task, said processor uses data identifying said first task's display window(s) to control display of said second task's display window(s) so as to be connected to and move with said first task's display window( s). The disclosed system has the advantage over the prior art in that it provides a visual connection between the windows of the first and second tasks which makes the display easier to understand.
