Does it timeout and eventually show or hang forever?

Is it waiting for a reply from a network drive?

TCHAR szFilters[]= _T("MyType Files (*.my)|*.my|All Files (*.*)|*.*||");
CFileDialog fileDlg(TRUE, _T("my"), _T("*.my"),
   OFN_FILEMUSTEXIST | OFN_HIDEREADONLY, szFilters);
if(fileDlg.DoModal() == IDOK)
{
}
