Confusing message from GraphEdit

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hello everybody!

I am facing a strange behaviour of GraphEdit while trying to stop the graph
with my filter.

From GraphEdit I press Run and Pause - works fine. But when I try to stop it
says "GraphEdit cannot complete pause within 10 seconds..." although it
takes it less than a second to display such message, it does not wait for 10
seconds at all!

I've overriden Pause and Stop methods in my filter to see if they are called
when I press Stop, but they are not called. I've written a sample program
that builds the graph and issues Run, Pause and Stop commands via
IMediaControl - they work without problems! Definitely the problem is not
about Pause or Stop and the error message of GraphEdit is confusing.

The only problem I found in my sample program is calling GetState never
returned S_OK, it always returns E_FAIL. Why? What does GraphEdit do inside?
Why does it displays such a confusing message without an attempt to pause or
to stop the graph?
