Stupid move to leave TNG. What other jobs did she have lined up? I would've stuck it out for at least three years. And if I was getting harrassed, like Gates McFadden was, I still wouldn't have quit. But I would've disconnected his spark plugs everytime he showed up for work.
Crosby did an episode or two of "Red Shoe Diaries", at least one where she was topless and even then she wasn't hot.
