Problem midi GP + Logic pro

Good morning,
I have a problem. When I open Logic pro while GP is open, no more midi messages are received by GP. I just want to use Logic in playback to work and play the GP patches.
Where does the problem come from?
Thanks in advance

What can you see in the Global MIDI Monitor Window of Gig Performer?
What version of Gig Performer are you using?

I just stated Logic while GP is open
From Ableton Live I am sending a MIDI Note and in Logic and Gig performer this MIDI Note is received via the IAC Driver.

So I cannot reproduce the issue.

How Looks your MIDI Ports Settings in the Options Window?

Thank for your response. It works now, I don’t know where it came from…a bug I guess
