We recently installed the CentraSite Community Edition (version 8.2.1). When working from Firefox (version 15.0.1), in the Asset Catalog / Browse window, we cannot select or deselect a single checkbox in the list of Asset Types on the left. Selecting or deselecting all of them at once with the overall checkbox on top does work, but not the checkboxes in front of the individual types. Are you aware of this?
From Internet Explorer or from Chrome there is no such problem…
