I keep saying one day I will give it another try.
My last try wasn't that long ago really, I have an old copy of MS Office 97 (told you it was old, but it does everything I need) and only MS Word and MS Excel installed. My gripe is that every time I opened a Word or Excel document OO's opening caused it to believe it had been changed and you got the pop-up save the changes, etc. etc. will be lost, yet the only thing that had happened was it was opened.
So actually opening a document converts it to be compatible or some such, so the alleged compatibility is a bit of a myth as it has to do some flip flopping around import .doc file, view in OO and either have to export it back or save as an OO doc (or an MS doc which it already was). I didn't want multiple variations of the supposedly same document which may have differences, so OO was history.
So until I bite the bullet and actually remove MS Office I don't see a future for OO on my system.
