Will Open Office do ok?

I just tested, and DOCX is working for me, along with all the other formats- Even if it doesn't work for you, TextEdit.app, which is shipped with the OS, has support for DOCX.

Provided, I'm on the Mac, so Apple probably has some support that the Aqua version of OOo is calling.

I use WinXP, I don't use Mac. Thats the diff, haha. I guess I Shoulda said the newest version of the Windows OOo. I just updated mine and it doesn't accept them, so yeah.
