it should be fine - all you need to do is download either the rpm or the .tar.gz file, burn it to a cd, and have your linux box read off the cd. it doesn't matter what o/s downloads the file, as long as the extensions are maintained. the only real snafu you might encounter is windows trying to save the file as a .txt file - in that case, you'd just need to rename it.

www.slashdot.org just posted a notice that StarOffice 6.0 beta is out.
