Anyone using Open Office?

I am trying it for the first time, and I'm hoping someone will know how to fix the two main things that are bugging me.

Namely, every single page has a stupid black border around its text that I cannot seem to remove, plus a "gap" between each page that I likewise am having no trouble eradicating.

This program is going to rapidly be deleted if I can't figure out how to undo this nonsense... (Guess what my two least favourite default-settings in MS Word are? Yep. Old!Word, anyway; we won't talk about the absolutely rage-inducing menus of Newer!Word, because I don't need a cardiac incident.)
