Hello Doug,
Thanks for sharing this information with us. We are expected a DOS build to go to test in the near future. I will make a note to have the test team look for the issue you are seeing. If you don't mind sharing could you please copy your tech support form here, so that we can try to match the system configuration? If you are not sure where the tech support form is, let me know and I will provide the instruction on how to gather this information. Where the keyboards that were used standard keyboards, or were they some kind of "gaming" keyboards?
