Always check for open and close events.
Send WM_APP message to thread to terminate it rather than TerminateThread.
Fix CreateThread/waveOutOpen race by waiting for background thread to

FILEOPEN95_OnOpen assumes that each item in the filter list returns a

unmarshaler routines of embedded complexes in complex struct and array
unmarshaling.
