The international releases of 4th Dimension version 1.0.8 and earlier DO NOT
run on a Macintosh IIci. The incompatibility stems from the copy protection
method used in 4th Dimension's international releases.
4th Dimension v2.0.8 is the Macintosh IIci-compatible international release.
(NOTE: The United States releases of 4th Dimension all work properly on a
Macintosh IIci.)
For information on how to upgrade to a new international Macintosh
IIci-compatible version, contact the distributor of 4th Dimension in your
country.
