Hi, when I open the media manager to search for pictures and doubleclick on a folder to browse through existing folders, the media manager crashes and I am back in the page builder. But after that I cannot open any property window or do some modifications. Also the page builder menu (top bar) is gone. To get rid of this state I have to hit F5 to refresh the browser with the result that all unsaved changes are gone. What can I do?
