[solved] Cannot expand/contract Sections in Admin Area

[tpohare]

Using CMS Made Simple with IIS7 when I attempt to expand/contract a Section with Content >> Pages nothing happens.
When I manually refresh the page the Section has expanded but obviously this isn't a viable solution.

This problem definitely occurs with Chrome, Firefox, IE7 & IE8. It is only occuring on one site using CMS Made Simple, on other sites using the CMS the section expand and collapse perfectly. The immediate differences between the 2 installs I can think of are:

- The faulty site was transferred from a different server while the working site is new
- The faulty site was upgraded from a previous version while the working site was installed directly on IIS7
- There are several additional modules installed on the faulty site

Thanks for any help on this.

Sorry, solved by copying the lib folder from a new download.
