This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
Its not so much of a bug now. The exam software warns you that your previous answer will be erased and you have to answer it again. So now your answer will be erased for sure I didnt touch any drag and drops that i had answered. I noted down all my answers anyway. You better do the same. It saves the agony of answering the question all over again.
