actually, i did try that, zach and T. I'm trying to make a decent rig for once, so i'm using alot of the techniques in this book.

i made two dummy objects, aligned them to the thigh bones, linked the thigh bones to them, and only the right one went screwy. very strange. I haven't been copying the IK. maybe i'll just delete all them bones and try again from scratch.
i even tried copying them, then opening the bones panel and clicking on realign and reset or whatever those buttons are at the bottom that are supposed to reset the bone. still happened.
i'll try again from scratch.
