Accents and punctuation in Spanish

[mcmultimedia]

Special characters can't be entered in Rev 2.1, accented letters that 
use diacritical punctuation can't be used in fields, these letters are 
important in many languajes.  Letters such as "á é í ó ú ñ ü" can't be 
used.
This limitation did not exist when using Rev. 2.1.1 or 2.1.2  in Mac 
computers using systems prior to Panther (Mac OS X 10.3).
Is there any way to resolve it? Is there a command to use?
