hhctrl.ocx的FreeLibrary在程序关闭时挂起的原因是什么？我怎么能避免这个？

I have got a program written in Delphi 2007 that uses html help. Very often it hangs on exit (even though html help wasn't actually called) and I traced the problem down to this call in the finalization section of Windows.pasI have got a program written in Delphi 2007 tha
