I did a week or two ago and it constantly crashed for me. I have about
30 plus machines here and I only tried it on one of them.
Was that with version 4.0 of LibeOffice? If so, that wouldhave been very
soon after 4.0 was released.
Generally I'll let a version x.0 "mature" for a while or wait until
there is a x.0.1 available.
I am currently using 3.6.5.2 and have found the writer and calc quite
stable. The only problem I had with 3.x was when I upgraded from 2.x and
several somethings in the profile didn't migrate properly and were
interfering with the built-in help and with the "recent documents" list.
I have some data in Microsoft Access, I didn't like the ad-hoc interface
to the "Base" part of LibreOffice, so the only part of Microsoft Office
that I license and use is Access.
I have ended up using Google Calendar, Thunderbird (email & RSS feeds),
Firefox + AdBlock Plus, LibreOffice for word processing and
spreadsheets, KeePass for storing and auto-typing my passwords at
various web sites, 7-zip, testing Gravity for usenet, but paid north of
$100 for Access because so far it is the best fit for a couple of
databases I have.
