I wish I could help but I'm having the same problem; it's driving me crazy! This reminds me of the excellent Adobe TV video tutorials for Edge Reflow. My only problem with them is that theyalways work every time on the screen, i.e., the problem you and I are having never shows up! It sure would be helpful if one of the staff would create a video that illustrates common errors/problems as they create aspects of a design. Regards & best wishes, Chuck
9/12/14 update: I have figured out my problem. One image element is so large that when I create the third media query, this image affects (messes up location) of several other elements. Yet I need the image to be large enough for the text on it to be read. I'm going to break the image into two sections so that I can place the halves side by side. That should work fine.
