misses very first MIDI-in packet?

CoreMIDI question:

my app sends a DEVICE INQUIRY REQUEST sysex and waits for a DEVICE INQUIRY REPLY sysex.

for some reason, my MIDI-in proc sometimes gets called with the reply sysex, and sometimes doesn't even though the MIDI-in status LED on the MIDI I/F (btw, it's a midiman 2x2) always blinks which i assume the reply sysex is actually received by the MIDI I/F.

fyi, my MIDI-in proc does get called for all the following MIDI-in's, it only misses the very first packet "DEVICE INQUIRY REPLY" sometimes, not always.

any ideas? suggestions? what am i doing wrong? am i supposed to wait for certain period of time after the app launch or the MIDIPortConnectSource() call?

thanks in advance,
katsura
