Updated to reflect the solution. In the original Fiddle posted in the comments, the z-index of the footer pane was -2. This was affecting the child elements as well. The form is now clickable after changing the z-index here to 3 as shown in the CSS below. Full code is on the jsfiddle.

CSS
#footer {
position:relative;
z-index:3;
font-size:0.8em;
}
The area was clickable when I put the original code on JS Fiddle, but when you typed, the text did not disappear.
EDIT: Fixed the information to properly address the question.
