Hi Stefan,
I'm coming back to you with the same issue regarding a blank file info panel.
The way we could trust the file with a cfg seems to not be always working and i wonder if there is another reason to not be able to get the info in the custom panels.
I also try to change the sdk version using the 3.6A instead of 4.6 for a panel created for CS5/CS6, but i stil get the same issue.
Sometimes the panel work and sometimes it doesn't.
I follow all the steps as explained in this post and pend many hours to understand, but i was not able to fix this issue this time.
Can you please open my mind in another direction to understand what's wrong ?
Best regards,
Daté
