After updating to Mac OS 8.5, my Japanese Language Kit version 1.2 with the Mac OS 8.5 update will sometimes switch to other language fonts in between English and Japanese ( English, Korean, simple Chinese, traditonal Chinese, then Japanese ). It does this in Netscape Communcator and Lotus Notes but not in Nisus Writer and some others.
Solution
The behavior described is caused by Multilingual Internet Access installing these other language scripts into the Mac OS 8.5 system folder. These language scripts are display only and will only be activated by a TCP/IP application. Therefore, the extra languages will not appear in most word processors(unless these language fonts are contained within a document) or other applications that do not use TCP/IP.
To resolve this situation, use the Mac OS 8.5 Installer program to perform a "custom remove" of the extra language scripts.
