Abstract: An object stack feature for graphical user interfaces can include a method for arranging items displayed in a visual interface into a stack where each item of the stack has a corresponding visual representation in the stack. The method can include in response to receiving an indication to stack two or more items displayed in a visual interface, creating a stack object comprising a list of the two or more items and a seed value for an ordered seed. The ordered seed can be supplied to an arrangement function that outputs positions for items in the stack object. An arrangement can be generated using the arrangement function and each of the two or more items can be displayed in the visual interface in the arrangement generated by the arrangement function.

Abstract: A method, program and system for administering tests in a distributed data processing network are provided by the present invention. The invention includes combining predetermined test content and multimedia support material into a single encrypted test file. The multimedia support may include visual and audio files for presenting test questions. The invention then exports the encrypted test file to at least one remote test location. The test locations import and decrypt the encrypted test file and load the test content and multimedia support material into a local database. The test is administered on a plurality of client workstations at the testing location, wherein the test may include audio questions and verbal responses by participants. During the course of testing biometric data about test participants is recorded and associated with the test files and participant identification.
