Occasionally, double-clicking on a MathType equation after an eXtyles process has been run will open an entirely different equation for editing. The problem is related to the save to RTF that’s performed “under the hood” by eXtyles. In some cases (which have not been clearly defined to Inera), saving a Word document to RTF (even without eXtyles installed) will cause this problem with MathType equations when the RTF file is then closed and reopened. To avoid this behavior, run the MathType menu function Convert Equations on the Whole Document with the type set to Convert Equations to MathType equations.
Note that this conversion does not work properly in some versions of MathType 5.x. It does, however, work in the most recent versions of MathType 5. Inera recommends any version of MathType 6.5 or later, up to the most recent release, 6.9.

Microsoft announced on June 10 that their monthly update for June 2014 includes 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.
A corrupt MathType object may trigger the following warning from Word during eXtyles processing:
Word was unable to write some of the embedded objects due to insufficient memory or disk space.
If the document has MathType equations, the warning may indicate that one or more of them is corrupt. To work with such a document in eXtyles, the corrupt MathType equation must be located, deleted, and re-keyed.
One strategy for locating a corrupt equation is the “binary search,” in which the corrupt equation is isolated by a progressive halving of the document. The procedure for a binary search in a Word document is as follows:
A MathType translation error-14 occurs when an equation has been set up in a manner that prevents proper conversion from MathType format to MathML. Often, but not always, this error occurs when an author has incorrectly used superscript or subscript in part of the equation.
To resolve this problem, each equation associated with the error must be corrected by hand in the Word document. Search for the following comment in the exported XML document and note which equation it precedes:
ERROR-14 IN MATHTYPE CONVERSION. PLEASE CORRECT MANUALLY.
The part of the equation causing this error will be missing in the XML version of the equation when compared against the MathType version. To resolve the problem, correct the equation in Word with MathType, using MathType operations that are compatible with MathML. Once the equations have been corrected, the manuscript should export without error.
Note: MathType 6.5 has an improved MathML translation that reduces the incidence of these errors significantly. If you are not using version 6.5 of MathType with an eXtyles XML export, we recommend that you upgrade. Inera recommends any version of MathType 6.5 or later, up to the most recent release, 6.9.
On rare occasions, when exporting a document containing a large number of MathType equations, a user will experience a Word crash. This crash is triggered by a bad interaction between Word and MathType, and it often occurs between the following stages of export: “checking paragraphs” and “Loading MathType translators.”
A workaround has been devised to preclude this interaction. The user should hold down the Shift key when selecting the export option and keep holding the Shift key until eXtyles displays this message box:
Once the box is displayed, the user may release the Shift key and click OK. The remainder of the export process will execute without issue.
Note that Inera recommends any version of MathType 6.5 or later, up to the most recent release, 6.9.
This problem can occur when authors insert equations with the Equation Builder feature in Word 2007 or 2010, but you’re using Word 2003 for editorial. The Word 2007/2010 equations are not backward compatible with Word 2003. Whenever you get a DOCX file:
At this point you can move the file into your regular workflow.
