Outside of your Gui constructor, none of the provided code actually
changes the values of the Gui box pointer attributes.  So, if you are
seeing them non-zero after Gui instantiation, and zero later, some other
code must be changing them, or a memory problem is overwriting them to
zero (hope for the former).
