before Gyration Inc. can compete in the Mouse & Keyboard arena , they must learn to design product that be completely in sync with Windows ! I even take extra step in download all driver need from the Gyration Website , but this slick and very design drive package still could not give a `` Ultra Performance '' . the keyboard would sometimes read and sometimes not ... and the mouse would force Windows to crash ! it be too bad , I want it to work . I guess I should stick to the `` Old School Products '' with more experience .
