My friend sent me his resume today from his Mac using Office 2004. I tried opening it at work. No go. It wasn't recognized as a Word doc. So I simply added the extension .doc and it opened fine. He is using Office 2004 Mac and Tiger. At work I use Office 2003 and Win XP. Here's the strange thing. When I get home the same file opens (is recognized as .doc). At home I have the same XP and Office 2003 setup? Any ideas? Thanks!
