Anyone have any good ideas on how to solve issues with storm doors not fitting well on shifting house? Recently installed a storm door and it no longer closes well due to not only shifting of the house, but also cold and warm weather extremes (live in North Dakota). Anyone know of a good storm door out there that isn't affected by the shifting as much? Any other ideas to help deal with the issue? Thanks.

The link here is a to a picture of a troublesome door latch that hoping I'm someone could advise on the approach to fix. [url]http://i207.photobucket.com/albums/bb153/sgull1/IMG_1000.jpg[/url] It's installed on an exterior door to a gift shop. The link here is to a parts diagram I found online of which I'm fairly certain is the particular model of Adams-Rite mechanism I'm having to deal with. [url]http://www.adamsrite.com/media/pdf/parts_manual/v2/45004700part-08.pdf[/url] What seems to be the issue is that the parts shown in the diagram called the "bolt assemblies" (part 9 and part 11 in the diagram) are failing to hold the door locked securely when the door is locked with the key. The door latch was subject to either some overuse or abuse as time has passed, and now it is possible to use a credit card to work the bigger size "bolt" open from the outside after being locked, and the smaller size bolt also doesn't seem to secure the door otherwise either, often getting stuck inside and not popping out when it should. If the internals of the mechanism are worn or damaged I can see that it's possible to acquire an exact replacement of this make/model latch (apparently it is called a "deadlatch" mechanism). However, with no experience installing such a latch or working with a door such as this, I have two basic initial questions: 1. To replace this latch in this type of "aluminum stile" door, how does it come out anyway? I really don't see any obvious screws there which attach it, other than the screws along the stile which seem upon initial inspection to be more involved with removing the stile off of the door. Is that what it would probably entail to remove/replace this latch? 2. In the photo you can see the end of the interior "crash bar" also installed on this door. With the latch issue as described above, would it be likely that the crash bar operation is also somehow involved directly with the malfunction, even if the crash bar otherwise exhibits no sign of unusual operation? Any suggestions/comments appreciated.
