^This sounds exactly like the problem I am having. However, a colleague of mine completed and the same exact form and I'm using his answers as a guide. So I believe that I am completing all the necessary fields in order to enable the signature field. However, when I click on the signature field it just flashes the blue highlighted color and does nothing. I have a currently valid certificate load from my CAC card. I know this because I signed another document yesterday. Please help. Technology shouldn't be this hard.
