Yeah, same problem. In the end, I just use Writer to do the
document and then before I send to anyone else, I use Word Viewer
to check first.
You could also try Google Docs. Haven't really used it that much
so not sure if you will have the same problem there.
There is also Microsoft Works SE (Sponsored Edition) in the
future.

But don't know when or if end user will be able to download it
themselves in the future.
