I'm not one to usually post on this thread, but just recently there's been a serious problem on my MBP and my mom's MB regarding e-mailing .doc/.docx/PDF files. I really need help ASAP because I'm trying to send out my cover letters/resume soon, and something's really not right here. Whenever I try sending her a Microsoft Office '08 Word document as an attachment, it downloads but not as a Word file. Instead, a folder pops up and automatically unzips itself with folders "_rels", "[Content_Type].xml", "docProps", and "word" inside; the file I sent to her is no where to be seen. In addition, when I try sending her a PDF, instead of the regular "Preview" icon on Safari's "Downloads" list, a white document with the top corner folded back shows up; I double click and nothing happens. I have to manually override it by forcing it to open the file via Preview. This is happening on my computer too (both 10.5.5 w/ Office 08), but here's the thing: it's been mostly hit-or-miss, with it not working about 90% of the time. Once in a while it will open up in Word/Preview. I'm concerned because my mom took her MB to the Genius Bar recently, and they weren't much of a help to her. This is really important because I'm sending resumes and cover letters, and I want to make sure that the people I'm sending these out to can open and read them. Any ideas as to what's going on? This did not happen before. Thanks for help!
