Rafa,
I have watched your video and have discovered that I am totally clueless.  When GG gets a chance, he will have to look at this and decide if it is doing what he expects it to and can explain it to me.  I have put a note on his computer to look at it -- I expect a very interesting response from him !  Phyllis

Today I have been looking at nesting EDL, it seems like a wonderful function, but I have found a problem.
Let me explain: When I open an .xml project in nested EDL mode, it loads in resources, very well, but if I open this EDL from there to make any changes, all the files of this project are loaded, which is very normal to occur this, so far so good, but when I close the EDL to return to the project, all the files get loaded, and this has puzzled me. I think the correct thing would be that when closing the EDL, only the files of this new project were left in the resources window.
Or am I doing something wrong again?
I have made a video so that what I quote is better understood.
