How kind, Seang! Thanks! Well, this is the first time I've encountered te problem, MartinC so it must not be too terribly pervasive; surely you don't need to write a whole test program for it. Now at least I know what to do about it. Perhaps a mention of the bug in the Read Me file for MacConverter and instructions to run these files through without the .rsr files would be enough unless one is there already?
