And I'm saying that if there is a script (and it's not a hover event) it was generated by SMT 2.0.
Look at your Insert Share Buttons extension in DW. There is a check box that says 'Hide buttons under a "Share" link.'
That is what was selected so if there is faulty code it was generated by SMT 2.0.
It sounds like you might not be aware of this possibly buggy SMT 2.0 feature.
