RE: MS Word does NOT do this!

Also, FrameMaker will *ask* you if you want it to save out a
file if it realizes it's crashing. This works in Un*x (of course)
and in MacOS(!!!), probably Windoze as well. FrameMaker's fallback
position is to create an "autosave" file that gets refreshed every
few minutes; even if the system locks up completely & FM doesn't
have a chance to save, you don't lose more than 5 minutes' or so
worth of work.

The mozilla talkback thing works in Windows so I guess it must be possible.
