Abstract: There is provided a user friendly display interface system for the interactive handling and sorting out of windows in complex window hierarchical graphical user interfaces. The system provides for the storage of a hierarchy of windows which are displayable to overlap each other in a selected order whereby a plurality of said windows are partially visible. Apparatus is provided for displaying on a display screen a plurality of these partially overlapping windows. A different audio identifier is provided and stored for each of these windows. Further apparatus is provided for moving around and positioning a pointing device, such as a cursor on the display screen, in combination with means responsive to the pointing device for announcing the audio identifier for each window which said pointing device enters. The pointing device may be a user controlled cursor, a stylus or even a finger in touch sensitive display systems. The audio identifier may conveniently be the name in the title bar of the window.

Abstract: There is provided a system for dynamically resynchronizing a storage system made up of a plurality of mirrored logical volumes respectively divided into a plurality of mirrored logical data partitions in the event of a system failure. Immediately after the correction of the problem causing the failure, means start to resynchronize the plurality of logical volumes but without waiting for the resynchronization to be completed; means access data from a data partition in one of said logical volumes. Then there are means for determining whether the portion of the logical volume containing the accessed partition has already been resynchronized, together with means responsive to these determining means for replacing the corresponding data in the other mirrored partitions in the logical volume with the accessed data, in the event that the portion of the logical volume has not been resynchronized. The means for replacing the data in the other mirrored partitions in the logical volume containing the accessed partition may replace the data prior to resynchronization of the logical volume or it may replace the data during the subsequent resynchronization of the logical volume. In the implementation where the data in the other mirrored partitions is replaced during resynchronization, then there is provided interim means responsive to the accessing of data from the data partition in said logical volume for indicating the partition as accessible and for indicating the other mirrored partitions in the logical volume as inaccessible.
