I'm thinking the greyed out file is because the author is filtering on a 
file type and didn't get the Mac syntax quite right, or something 
similar. That's the most common reason why a file would be greyed out in 
the file dialog.

That doesn't explain how it could save the file in the first place 
though. The only thing I can think of is that maybe the file was 
pre-existing by accident. Secure mode is supposed to block all file 
access, and I think it works correctly.
