Gotta love it.
I usually manage to get something nasty and loose my O/S about once a year. Usually takes about 6-10 hours to get everything working properly. Done it so much now I don't even get aggravated anymore. Just grin and dig in. It will teach you patience and I learn something every time.

Hmm...I do wonder how much fun it would be to launch all the scrap arrows into a computer though?? I think it would be very satisfying.
