As far as i know - it *should* have. Not save/overwrite the old
file,
just create a new temp one. Which is detected in case of of chrash, and
recovered.
As far as i know, OO does this, MS word does this - even vim does this!
That is why you can recover documents never ever saved.
But i have seen cases where it haven't worked - looks like OO haven't
detected where the file was. Or it was never created.
When that is said, i have used oo for about 1½ year now, and can only
remember two bad crashes - and in only one case i was unable to recover.
I remember cursing word many, many times more
Then have did my spouse run into a bug? The system was overloaded and
soffice.bin was killed due to an out of memory condition. I expected
that OOO would have recovered from this state in some way, but I could
not determine where the backup/temp file was.
