Ok, you hear a ding, and you see the little icon. Something that looks like you have gotten mail on top of the little airplane icon. You click that. There should be a little message highlighted in blue. You click that. That should, open up a new window, that will take you to the fares, they have available for the ding.
Did you put your desired location airports you are interested in getting dings from? For instance I list Long island, NYC, Orlando, Chicago, California, Norfolk, any place I desire to travl in my setup. If you have not done that. That could be the problem.
