Word is completely lethal these days, it just seems to explode for no reason from time to time. Mind you, not everyone has the problem and I'm pretty sure it's down to changing *any* of the default options. In particular, I know if you turn off all the auto features, it'll ocasionally detonate when you backspace at the start of a line.

I guess it's down to the way they code...write crap and test extensively, fixing up the problems as they surface. So if you go down any of the less tested paths, you get to test the bits they couldn't be bothered to.
