Assume this refers to builds of FB5. Do you know the build # when it  
stopped working?

Please supply some basic environment information Mark( which release  
of OSX?, which version of FB5, Intel Mac or PowerPC mac ). It will  
help rule out things.

by "all I see" does this mean the rtfs display as text within your  
app? If the same rtf as displayed by the app ( and is presumably in  
the Resource directory within the package ) is opened in TextEdit,  
does it display correctly?

Has this application gone through any OS X upgrades recently? Noticed  
some posts <http://forums.mozillazine.org/viewtopic.php? 
f=38&t=1461325> complaining of similar issues.  There is also a series  
of atsutil commands in that post that were suggested. Not sure if this  
is the problem you've encountered but having more information will help.
