A program closes when you move the mouse pointer over the program file in the Open, Save, or Save As dialog box on a Windows XP Service Pack 2-based computer

You move the mouse pointer over a program file in the Open, Save, or Save As dialog box on a Microsoft Windows XP Service Pack 2 (SP2)-based computer. After you do this, the program abruptly closes.

Note For more information about how to reproduce this problem, see the "More Information" section.

This problem occurs if you use a program that implements the shell column provider feature on your computer. For example, when you install Adobe Reader 7, the shell column provider file (PDFshell.dll) is installed on your computer.

An access violation occurs because Windows tries to reference the pointer of the shell column provider without loading the shell column provider. Therefore, the program closes abruptly.
