I've never understood why Director has both a "Save" command and a "Save and Compact". When would you ever want to do a Save without also doing whatever it is doing when you save and compact (when you don't compact, you're just keeping a lot of excess bloat around).
Anyway, I bring it up here because I just realized that if you keep saving a castlib over and over to the same file name, you will get that same kind of bloat creep. I highly recommend that you save to some other temporary filename and then save back to the original filename to avoid this. (Unless or until Adobe changes this behavior.)
