Janet,

It sounds to me like you are better off for moving on.  From what you described, my perception of the problem is somebody was threatened by your abilities.  It's sad that people can't get over the fact there are other people that have more skills and are better at one thing or another.  They would be so much better off in the long run if they looked at that situation as an opportunity to learn and get better rather than be afraid of being looked at as not being able to do something as well as someone else.

In the big picture, are technical skills really what define us as a person?  I think not.
