Ah, I vaguely recalled that you once said that. Anyway, using new thread (at each object creation, right?) sounds scary to me. How do you manage to clean-up those threads at unload time? How you call the created objects, which reside in the different thread(s) from the calling thread, i.e. PP's main thread? Thread switch or marshaling or etc? I can imagine one scenario which crashes PP at com.unload(). In which thread do you call CoUninitialize()? It should be the new-thread, but if mistakenly call it in the main-thread, it could crash PP.
