SYMPTOMS

When you run a Microsoft Foundation Classes (MFC) application on a computer that is running Microsoft Windows XP with Service Pack 2 (SP2) installed, you may see memory leaks for Graphics Device Interface (GDI) objects when you create and destroy child windows. To see the memory leaks, view the GDI objects of the process in Task Manager.

This problem also occurs on a computer that is running Windows Server 2003 when the Themes service is started. By default, the Themes service is disabled on Windows Server 2003.

CAUSE

This problem occurs because of a bug in the implementation of the new theming interface.
