OK, so I downloaded the latest version of Libre Office (for Mac OSX 10.6.8) but my document will only open in Open Office (with that familiar blue "Oracle" opening logo-box) and the .odt file extension. What extension is Libre supposed to have? Is it also an .odt?

I got no "open with" option - it just automatically comes up in Open Office even though that's not my default application; and when I try to "Save as…" it only gives me Word (which I have installed on this machine) or Open Office. No Libre in sight. I don't want to uninstall OO because I still have too many things in it (yes, I know I could open them in Word but have reasons why I don't want to right now).

I clicked "Text Document" straight from the Libre Office menu that offers all the various choices (text doc, spreadsheets, database etc) but can't seem to get it to BE Libre Office. What am I doing wrong?
