[vtkusers] Error during cleanup: wglMakeCurrent failed in Clean()

[Francois Bertel]

error 6 is ERROR_INVALID_HANDLE

ref: http://help.netop.com/support/errorcodes/win32_error_codes.htm

the line vtkWin32OpenGLRenderWindow::Clean() that triggers this error code is:

wglMakeCurrent(NULL, NULL);

According to the spec, NULL is a valid handle. Maybe it is a bug on MFC side?
Which Windows version/Visual Studio do you have?
