I have to agree with the others about the corn freaking out because of a husbandry issue. I keep both corns and ball pythons and I have them housed in a different rack. I used to have them on the same rack, but I had two independently controlled flexwatts - one per species. That way I could keep the ball pythons at their hot spot and the corns at theirs.

If your temps in your rack are designed to meet our ball python's needs, then it's much too hot for corns. I keep my corns at an 85-86* hotspot with the cold side 70-75. Anything above 90* for a corn snake can kill them if you aren't careful! They are very sensitive to hot temperatures.

If you are using the same husbandry, I would recommend you get another rack system for your corn (s) or use a tank. Corn snakes can do well in tanks with a heat lamp (I have one set up this way) or a UTH. Also, i recommend this book: http://www.amazon.com/Corn-Snakes-Co.../dp/1882770706 It's a great took for learning to care for corn snakes and it's very comprehensive. It even has a little bit of a morph guide.
