Thanks for the tips. I have been going to the terminal and typing - 
chmod 644 *.pdf-, which takes care of the problem quickly enough,  
too. I'm really confused that changing the layout changes the  
permissions. I'm guessing that some temporary file gets made which is  
set to the bad permissions, and then the bad permissions persist as  
the temp file gets moved.
