Hi Vieira, I respond to your private message about getting more answers to this older question.
Feel free to "bump" your post: just post a reply so that it comes back up on the list of topics and gains new visibility.
Also the easiest way for people to help is if you can attach a very simple Logic project that exhibits the issue you describe, and give the steps to reproduce the issue. Then I or someone else can download the project, experience the issue for ourself, and experiment with it to try to find a potential solution.
Hope that helps!
