It's- a me again!
I'm sorry, I will delete all previous versions of this post once my issue is settled once and for all.
I'm only posting again because I have no way of knowing otherwise if my renewed question will ever be seen.
Chapel answered me in here, making a new version of his macro <<message>>.
The issue I have is the fact that it works well with one <<message>> macro displayed, but if I have something like
<<message "Statistics">> Statistics <</message>>
<<message "Objects">> Objects <</message>>
Then whenever one is opened, both open on the next passage. Would there be a way for the macro to remember which <<message>> has been opened, and which hasn't ?
Thanks a lot. Sorry for overposting.
