Easy Blogging and eNewsletter

I’m using eNewsletter within a Easy Blogging set up (modified as per https://premium.wpmudev.org/forums/topic/grant-e-newsletter-permissions-to-editors#post-262453) there’s a problem with the create new newsletter. The tabs aren’t working properly, the script isn’t setting them as display:none, so I get one long page as oppose to the tabbing and the function buttons don’t work – “Send Preview” etc.

Please advise
