Mouse up to show field not working
I have a standard form where there is a portion of the field which has pre-drawn lines for the form.

The lines need to stay for those times the form is printed and filled in by hand. However, when completed by computer, I want the lines hidden so the multi-line text typed in is not obstructed by the lines.
My thought was to make the field with a white fill background, which would hide the lines, and have the field only visible when clicked on, and then it could be filled in. Here are the settings I selected:


With these settings I am unable to click on the field at all, so this part of the form can't be completed. I would like to get this working, or if there is a better way to accomplish the same goal I can give that a try as well.
