Whenever I open up documents in Print Layout View that were created under earlier versions of Word (2000, 2003, 2007), Word replaces several of the fonts with something that looks like Arial bold. Sometimes it changes just the title fonts, sometime the entire
body font--it's not always the same phenomenon in each document.
The Font window on the Home tab still shows the name of the original font being used in the document, but the screen does not show that font--it just shows whatever it replaces the font with.
Office was upgraded from Office 2007 to Office 2010.
