As of July 7, 2011, I cannot expand parent listings within the Table of Contents sidebar on the Structural Analysis and Design Wiki. I receive a Loading message, but it never shows the child listings. A screenshot of this behavior is shown below. Can anyone else reproduce this problem? I'm running Internet Explorer 8 under Windows Vista.
Yes, there was some maintenance applied to the site on July 7 that resulted in this (unexpected) side effect. The good news is that this is temporary and has a workaround. If you click on the parent title (and not the +), the section should expand. From then on, clicking on + or the section parent title should work.
