I've got a program that uses the midi multimedia functions to 
communicate with external MIDI instruments. I can open a device
and receive data, but I can't close the device when I'm done.
My first code looked like:

	midiInStop(hMidiIn);
	midiInUnprepareHeader(...);
	midiInClose(hMidiIn);

When I called midiInClose() I got a MIDIERR_STILLPLAYING return
code. A bit of research in the help files revealed that any
input buffers added to the device would cause this return error,
so I modified my code to:

	midiInStop(hMidiIn);
	midiInReset(hMidiIn);

		... wait for my 3 buffers to be returned

	midiInClose(hMidiIn);

If I step through the code, all my buffers are returned, but now
when I call midiInClose() it never returns, and I have to reset
the program. Anyone got any ideas what is going wrong?

Thanks in advance

George
