Программа для рисования интерьера комнаты (ОЧЕНЬ ОЧЕНЬ УБОГАЯ).

Для представления стола, тумбы, картины использованы собственные классы (с двухуровневой иерархией).

Предусмотрена возможность вернуться к редактированию любого объекта.

Проблема одна - программа НЕ РАБОТАЕТ.

Несколько опытных (более трёх лет программирования на Delphi) просмотрели целиком и полностью код программы, НО при вызове конструктора объекта возникает ошибка.
