I’ve had a couple of people tell me about the issue with the weird things that happen when editing a post/page, but not about the theme options. The author did actually stop by one of my comments on ThemeForest and said that this he believed this was because of a conflict with another plugin people are using. But for the life of me, I can’t remember what that is now.
If you’re having issues specifically with that plugin, you should contact the author. He seems to be pretty good about wanting his plugin to be bug-free and work right.
