The actual title of the patent is: "Display System and Memory Architecture and Method for Displaying Images in Windows on a Video Display" Sort of reminded me of the logical devices under IBM VM except it actually allows direct access to the physical device. An interesting concept but since it inherently relates to the introduction of multitasking and device sharing, it will be interesting to see if another vendor challenges it. -- Regards.....George Hart, Computer X Canada Ltd.
