Thank you for your interest Bouke, I ‘ll keep in mind your notifications, (that was my first editing -I’m a director, usually I just give orders to somebody).
Any way, the good news is that the problem is SOLVED. I am not sure how, but I will put here my guess for the next despaired director. Maybe, the fact that I opened (for the 10th time) the edit caption, and without changing a thing –Noting at all- I closed it again, using the ok command instead of cancel made it work.
As magic it’s not my style, is the only explanation I can think.
Now , I’ll have a look on your subtitling app!
Thanks a lot!
