Check the ownership and permissions of a directory called "Claris" in the
global System Folder. Along with other Claris applications, FileMaker
stores temporary files in a folder called "Claris" in the current System
Folder.
If the folder doesn't exist, FileMaker creates it and starts putting
temporary files there. However, new files and directories under A/UX are
created with a default user mask. This mask sets the permissions on the
file or directory to allow write permission only to the user who created
the file or directory. As a result, the first account to use FileMaker
would have a Claris folder created, but only that account could write to
it. The solution is to change the permissions on the Claris folder to
allow read and write access by everyone.
