We've duplicated the problem you reported with the Hebrew Operating System
(OS) and believe to have found the workaround.
After you've installed both the Network Software Installer and MacTCP on
your Macintosh running Hebrew 6.0.7, prior to configuring MacTCP you'll
need to do the following:
1) Via the Hebrew Interface System Control Panels device, select left-
to-right.
2) Select the Roman Script Manager (click on the Hebrew "Star" and the
Roman "Diamond" will appear in its place).
After configuring your Operating System in this fashion, you should then be
able to configure MacTCP.╩
