I am having some difficult volume refnum trouble.  I have a situation where it
is necessary to store the parameters of certain files into my apps prefs file
so I can easily access the files from a menu (much like ResEdit's Open Special
menu).  If I'm running my app and add a new file to the menu, I can open that
file from the menu with no trouble.  Before quitting, I store the file's
name and volume refnum in my prefs file.  When I restart my app, I can no longer
open the file - the vol refnum is the same as when I stored it, but the system
can't find the file.  If I reload the file, I find that, sure enough, the vol 
refnum is different this time around (which explains why I can't reopen the
file when I restart my app.  What else do I have to store in my prefs
file?  Am I storing the right stuff (file name and vol refnum)?

As always, any help is much obliged.
