Arabic Language Kit and NISUS Writer, as well as MarinerWriter work just fine on the Mac - and there is always Simple Text!. On Windows you should use Windows 2000 and do the appropriate settings for Arabic and use Office-Word - I have not tried it, but it should work. Mac users need to make sure that they only install those language kits that have been released for their particular system, i.e. the old language kits do not work on 9.1 - only those coming with the 9.1 system will work correctly.
