Ha, same here, batch mode saved me hours on my grandma's old albums.

Bought a cheap vertical mouse a few years back after my hand kept going numb during long design sessions, and it felt weird as hell for about a week. Stuck with it though, and the tingling in my fingers calmed down a lot. Not the same as sectioning hair, but the wrist angle thing seems to be the common thread with this stuff.

Hate that you had to see that mess first thing with your coffee, nature is brutal like that. Hawks do tend to swing back through an area once they know it's a good spot for an easy meal, so keep an eye on your fence. Sorry about the feathers all over your yard though.
