Rereading your original mail...
You hit the "Test" button on the Advanced tab, with the format you want
selected...
And a pin is being created, and even getting as far as KSSTATE_PAUSE...
And *then* you're getting format-support queries?
That's pretty weird.
What format is being passed to the pin creation dispatch routine?
I assume the format support queries are still targeted to a filter handle, not
a pin handle.
Can you grab traces and send them to me? This isn't a glitch /per se/, but the
instructions are the same:
