>>Using a member property avoids any possible side-effects normally found with a PUBLIC anything - the odds are that you're issuing a PRIVATE statement using a wildcard that hides the array, or are deallocating the array using RELEASE in an unexpected location. With member property arrays, the reference is scoped to the object (in your case, a Form) and won't suffer side-effects found with PUBLIC/PRIVATE memvars.

Your problem has nothing to do with the amount of memory used by the array.
