Hi, 

I have tried to use two sample plugins (PrefilterPlugin and InputPlugin) on my SUSE Linux 10.1 box. After succesfully compiled both plugins as shared library and copied over to bin/plugins directory, they are working. After the RMACreateInstance are called, only QueryInterface are called with many iid's not being implemented. After that,  the  agents's objects are simply destructed by the producers' core and the shared library is shut down.

It seems like the reason for shutting down is due to all the unknow riid passed in for failed QI calls for the plugins, but why the actually implemented interfaces by the plugins such as IID_IHXTConfigurationAgent, IID_IHXTTransformFilter, or IID_IHXTInputFilter are never queried? thanks for any suggestions.
