SYMPTOMS
When you move or resize a window, a program that uses OpenGL may perform an illegal operation, and then shutdown. For example, Microsoft Internet Explorer may generate an invalid page fault if a Java tool using OpenGL is running, and the window displaying the OpenGL graphic content is moved. Also, the following message may be generated in the Details section of the Application error dialog box:

caused an invalid page fault in

module OPENGL32.DLL at 0167:78abbcf.

Bytes at CS:EIP

83 b8 24 2a 00 00 00

NOTE: The "Bytes at CS:EIP" data in the Details section of the Application error dialog box on your computer must match the data in the error message listed earlier in this article. If the data does not match, your computer is not experiencing the problem described earlier in this article.



CAUSE
This problem can occur if you do not have a hardware accelerator adapter that implements OpenGL, and the program uses the Microsoft software implementation of OpenGL. Because of this, the message loop for the program is running on a thread that was not initialized for OpenGL, causing an invalid page fault error message when attempting to obtain access to the OpenGL context for the thread.
