Where can I find this xorg-composite.conf file?

If I create a file with that name, I can add to the project and it 
appears there. What is the "Exclude from project" line in Project 
Properties? Do you have read/search access to that file?

I re-ran the steps to produce the bug and found I didn't provide enough information.

File Locations:
/home/myusername (my user folder)
/home/myusername/website (folder keeps all web files & subfolders)
/home/myusername/website/linux (folder holds linux-specific pages)

Procedures:
I click on the linux folder on the file tree and open something in the folder.
Project>Insert Files and browse to linux folder, select file.
Hit "OK" and the file adds to the file tree just fine.  That is the reply you sent me and it works as expected.

Project>Insert Files and browse back to /home/myusername to select a file, any file.
Hit "OK" and the file fails to appear in the project file tree.  No error message either.  It copies itself into the folder of my project, but does not appear in the project.  I checked the directory contents and verify that it's copying.  Maybe I'm wrongly assuming that I should be able to select a user file from anywhere in my home folder?  

Project>Insert Files and browse back to /home/myusername/website to select a file, any file.
Hit "OK" and the file fails to appear in the project file tree.  No error message either.
