This is the place to discuss bugs that have been found in the most recent version of PivotX. Posting bugs will ensure that the Development Team is aware of them and that they will be addressed when resources are available.
After installing PivotX 2.2.0, I noticed some strange behavior of the navigation menu in the back-end (see screenshot). This happened in my Chrome browser, but also on IE7, Opera 11, etc. It seems only to occur when your on the 'Manage Media' page, and hover over another navigation link in the menu.
It is an upgrade. Your comment made sense, so I re-uploaded everything, making sure to overwrite all files. The problem persists though.
Further troubleshooting leads me to this:
When I click on (for example) 'Entries & Pages' in the menu, the <li> for that item gets the class: <li class="parent sfHover sf-breadcrumb">. The 'Manage Media' item gets this when active: <li class="current parent">. All the other items act similar to the 'Entries & Pages' navigation item. Not sure why that is, but it seems wrong.
