FIX: ImageList Class Leaks GDI Objects (813967)

SYMPTOMS

When you use an ImageList class in a Microsoft Windows Forms application, the calling process will leak some GDI objects for each new instance of the ImageList class. When the number of GDI objects runs out, any later operation that requires an allocation of a new GDI object fails.

The type of failure depends on the type of operation that is requested. Typically, an OutOfMemoryException error occurs. You can view the number of GDI objects that a process uses in Windows Task Manager. To do this, click Select columns on the View menu, and then click to select the check box for GDI Objects to add the GDI objects count to the default view.
