Jeanne A. E. DeVoto,

Thanks for a good and precise answer. A supplementary question: We are using
 ----if platform() is "MacOS" then ... etc. ----
to check before using som exts that require Mac OS 9. But how can we
determine if the system is Mac OS 9 or Mac OS X?

Best regards

Ps. You should considder implementing a dialoque warning people when using
the wrong Mac Rev-version of 1.1.1 on the wrong Mac OS.
