If double-clicking from the email program is not working:
Try saving the file to hard drive and use File | Open to open it. Leave File
| Open set to "any word document".
If you normally can see .doc extensions and this file doesn't have one, you
may need to add it manually for double-clicking to work.
PS. CyberTaz, it is not possible in MacWord 2004 to save a doc in WinWord
format. There is no such thing, because it's been the same file format
since Word 97, although certain features are version dependent, and Mac to
windows might run into similar problems as Word 2003 to Word 97 would
encounter. All the Mac user needs to do is make sure the file has a .doc
extension and use windows-friendly email attachments, and not use periods or
slashes in the filename.
