Here's a slightly wacky solution that I just tried and works not badly. It doesn't make true shuffle, but it would introduce some randomness. Create a navigation pallet out of small squares. Enable hyperlinks on each of them, one linking to each page. Set them all up in a nice neat array with no space between them and no border so that they look just like one rectangle. After setting all the hyperlinks, group them to make them easy to transport. Then paste this group onto each of the pages. Then when you are viewing your flash cards instead of just clicking anywhere on the card, click in a random spot of the palet. For a fancier version, take out the fill and make it invisible and cover your whole screen and close you eyes and click. You would just need to use the right arrow key for showing your answer.
