DialogBox crash in Win7

Question

I have windows application developed in VC++. I am using a CFileDialog to display a dialog box . However the moment I right click on the dialog box , it crashes . The same code works fine in XP . I read some where that the Vista Style is no longer supported . So I modified the code as follows. Still I get a crash

CFileDialog dlg(FALSE, _T("*.xml"),strFileName ,OFN_HIDEREADONLY, 
                         _T("(*.xml)|*.xml|(*.*)|*.*||"), NULL, 0,FALSE);

if (IDOK == dlg.DoModal()) //crash here on right click
{
        //CString folder = dlg.GetFolderPath();
        strFileName = dlg.GetPathName();
        SetFileName ( T2CW (strFileName)); 

}

Following is the stack trace

Answer 1

The issue gets resolved if I disable the NVDIA CPL Context Menu Extension from the context menu . However its still a mystery as the same code does work for other applications .
