Improvements and fixes

This security update contains improvements and fixes for the following nonsecurity issues:
  • Translates some terms in multiple languages to make sure that the meaning is accurate.
  • When you try to print a document in the envelope paper size and the landscape orientation in Word 2013, the printing is blocked and the document is set as the letter page size in the spooler file.
  • The track changes bar may not appear in the correct position in Word 2013.
  • Assume that you preview a Word document in the preview pane in Windows Explorer. When you print a document that contains comments in Word 2013 during this time, the comments are not printed.
  • It takes a long time to run a macro to implement some revisions in Word 2013.
  • Assume that you formatted text as right-to-left in Word 2010 using the built-in RtlRun macro, and that this text contains text in Latin characters. When you open the document in Word 2013, the text is displayed with the letters in reverse order. For example, "txeT" instead of "Text."
