The present invention enables the management of arbitrary regions of a window. A surrogate window is created to contain a region of interest in a source window. A surrogate window may also be shared among multiple devices. A user may interact with the content in a source window or its surrogate window(s). A surrogate window is updated to reflect any content change in the region of interest in the source window. In the case that a user resizes a surrogate window, the entire content of the surrogate window is scaled accordingly so the entire content remains visible.
