i've felt like throwing my computer across the room countless times, but never my 1000. Thats one of the reasons i like it so much is that it's a dedicated piece of hardware, unlike a computer which is much more likely to send me on a killing spree of frustration and madness

.
I've only ever had my 1k freeze when i had a problem with my load screen from the cf card, that was just a bent pin in the cf card slot.
So this sounds very weird to me indeed.
I've stuck the words "have you saved recently" in big letters just under my monitors to remind me, and try to save after any small changes at all in my tracks, although this can be quite time consuming sometimes i must admit.
