Abstract: A method for managing simultaneous display of multiple windows in a graphical user interface (GUI). A computer system with a display and user interface input device displays a primary or container window on the display, comprising a predetermined region for displaying information and/or receiving user commands associated with a first computer process. The system displays a target window comprising a predetermined region for displaying information and/or receiving user commands associated with a different computer process. The target window is typically displayed in a higher z-order relative to the primary window to maintain it on top. In response to a predetermined triggering condition, the target window is manipulated by movement, temporary disappearance, and/or size reduction, while maintaining the relative z-order of the target window relative to the primary window and away from a predetermined avoidance region associated with the first computer process.
