Start a new game and don't answer any of the questions. Instead, listen -- if no one answers, then read the answer. Keep a record of the it under the category and price. Once the first session ends, save the game. Return to the game and you will have all the answers. This can also be done for Double Jeopardy.
After Alex reads the question and the small stop sign at the bottom appears, press ESC and count to 15. Click "Resume", the time should be out, and the computer will be able to answer. Note: Don't do this if you know the answer to the question.
