Using winXP service pack2, Office XP. Full privalages on this comp.

I have a "Word" file that I want to put on a CD-RW disk. When I went to save this file to the cd-rw, it would not work. I saved it to the hardrive, and then saved it to cd-rw. It was saved as a read-only file, but I was not prompted for this option. I cannot delete it from the cd-rw.
How can I delete it? Or change it to read/write?
How can I save to cd-rw without saving to hardrive first?
Is there a setting, so it will not be saved as read-only?

Any suggestions would be appreciated.
