I have a simple windows plug-in that's loaded within an HTML page, being embedded using <OBJECT> (it has height and width). It does not create any hwnds, it just is an empty shell that returns NPERR_NO_ERROR (or 'true' or whatever success indicates) for everything.

It's NPP_HandleEvent() function is never called (it is set in NP_GetEntryPoints()).

This is correct. NPP_HandleEvent is only called for windowless plugins. By default plugins on Windows are run in windowed mode where you subclass the window from NPP_SetWindow and handle the messages directly.

If you want to do a windowless-mode plugin you need to explicitly tell the browser that decision:

NPN_SetValue(instance, NPPVpluginWindowBool, (void*)false);

You should check first to make sure that the browser supports windowless mode. See http://mxr.mozilla.org/mozilla-central/source/dom/plugins/test/testplugin/nptest.cpp#939 for some sample code from our testplugin.
