Hi Ron--
Try turning the "saverenames" option to "off" and see if that helps. That will tell Arbortext to simply save over the existing file, instead of saving to a temp file, removing the original, and then renaming the temp file. If this works, and you want to ensure that this setting applies to all your users, you can add the following line to your init.acl file:
set saverenames=off;
