Reply to Bug(?): sometimes it "misses" a press? (OSX)

Hi good people,

I just took receipt of my Midi Fighter and it's fantastic.

But, I was wondering about one thing: has anyone ever noticed that sometimes the first keypress in awhile doesn't register?

In other words, if you set the thing up and are playing it for awhile then you let it sit -- then trigger it again, sometimes the LED triggers, but no MIDI event happens until second press.

Am I imagining this? Has anyone else noticed it? I'm not opposed to digging in the code myself but wanted to check first.

Thanks,
