I'm running DMX 5.1.0 on a DNN 4.8 install. I'm finding odd behavior on the main menu options (Folder, Search, Help). You must click an item (such as "Folder") to get that menu item to open, but then if you don't select an option from the menu, it stays open. Clicking "Folder" again won't close the menu as you might expect it to. Is there a way to change this behavior?
