Abstract
A porthole window system for computer displays allows a user to look at a portion of a window which could otherwise not be seen. A porthole window acts as an opening in a window of the usual type through which underlying windows may be seen. A porthole window can have different features as desired, including links to selected source and target windows, real time movement on the display screen, and the ability to be updated when a target window is updated. The porthole system runs concurrently with the normal window handling system of the computer.
