Microsoft announced on June 10, 2014 that their monthly update for June 2014 included an important fix for eXtyles users of Word 2010 and Word 2013. The fix corrects a problem when DOCX files with Microsoft Equation Builder math objects are processed with eXtyles -- in a small number of cases, one or more Greek letters in such equations would turn into Roman letters due to a bug in Word's Save to RTF capability. Inera reported this bug to Microsoft in September 2013, and through the efforts of Murray Sargent on the Microsoft Math team, a fix for the bug was included in the June 2014 Microsoft monthly update.
Word 2010 users need to install the update available at http://support.microsoft.com/kb/2881059
Word 2013 users need to install the update available at http://support.microsoft.com/kb/2881005
Users of Word 2003 and Word 2007 are not affected by this bug and do not need to install any update.
Inera strongly advises all users of eXtyles and Word 2010 or 2013 to install this update immediately to protect the integrity of any Microsoft Equation Builder objects in documents they process with eXtyles.
