Crashing buzz on windows 7 like we did on windows XP

[vacuum]

When I used old buzz on windows XP and it crashed, there was often a bit of time to quickly save as... a new bmx.

Are there settings to adjust to be able to have crashes like that again (for both old and new buzz).

Edit: Can windows 7 handle buzzcrashes like win XP did ?? so that there's a little time to save.
(Sorry for the kind of strange message title..)

Use automatic backups (View -> Settings -> General -> Automatic backups.)
But if you can crash Buzz you're doing something very wrong.

I ask for old buzz mainly.
I use automatic backups. Buzz seems to not backup the bmx fast though.
(or maybe I'm used to saving very often, so that it doesn't backup)
Can it be set to backup a little faster ? (edit .xml oslt ??)

..doing something wrong?? Now that you say so, I should update PVST .
I don't remember why I had sometimes crashes with the later builds, but it was
not a big deal.
