WTF??? She quit because Hurley harrassed her plain and simple! Hell, it was so bad Patrick Stewart had to tell him to back off.
And, what's with bad mouthing Roddenberry???? You have no evidence to support the fact that he approved of this behavior???
As someone who has been sexually harrassed I can say that the harrasser was the only one doing the harrassing and not his friends.
When Hurley left, Gene invited her back. And she stayed for the remainer of the show, so if that doesn't prove that Gene left her alone, I don't know what does.
