I cannot Pack and Go or even save from within my Publisher 2007 document because one font in my document-Myriad Condensed Web- is preview only. I don't recall using that font when creating the document but I did import some files. I solved the problem by saying yes to a "do you want to substitute" screen after first making a copy of the document. Is a way to search the copy for that font so I can check the substitution? In general, is there a way to search a .pub to check which fonts are used where?
