Buddypress Sliding Login Panel not working with WPMU Blogs.MU theme

Hi all

I am running Wordpress 3.2.1 and Buddypress 1.5

I downloaded the sliding panel login as created by Sarah Gooding in her article here:

https://premium.wpmudev.org/blog/new-sliding-ajax-login-panel-plugin-for-buddypress/

However, with the blogs.mu theme that I downloaded from you, the panel does not slide down. The panel is functioning as the tab changes from "My Account" to "Close Panel", but nothing slides.
All the JS files are there and referencing the right divs. I even checked it with the default theme and it works fine (you have to tweak z-index, but hey no biggie).

Please can you help me understand why the blogs.mu theme is breaking this superb plugin. I really would like both of these to be compatible so your help would be greatly appreciated.

Thanks

Rob
