The users can register directly on the site by clicking on the register button and filling out all required fields address, phone, etc, etc. Or the user can purchase products with out register using COWOA Updated and Combined "Guess Checkout". I have made no changes with the customer address book unless guess checkout query has conflicted with admin new orders in the DB. I also have Ty Package Tracker installed but I merge the files careful so there is no conflict between those 2 modules "Admin New Orders."
Can you compare your version of "query_cache.php" with the stock one in Zen Cart 1.5.1?
I did compare the files everything seems collect.
