I use the hypatia sans font developed by adobe. However, since starting to use Word 2010 the font exhibits unstable behavior within word documents (not excel or other office 2010 products). For examples see below, all of which occured while editing one document .... anyone know what might be causing this? This problem did not occur with Word 2007.

Example 1...original correct condition upon opening file

Examples 2 through 4 .... things that happened to the document while editing
