Rocky,
Is the entry door inside panel wrapped in vinyl or is the panel vacuum formed plastic? If it is wrapped, you can remove the panel from the door carefully. You will have remove the window trim and everything that is securing the panel. Using a hair dryer, you can warm the vinyl and restretch it around the edges and secure it with 3M-08090 spray adhesive. If you have a hand stapler, add 1/4" by 1/2" wide staples around the perimeter for extra strength. It is about a 4 hour adventure. Fred
