Hi, I made a custom menu on the top of the website with: home - about us - categories and contact us. Now, the categories folder.... if you hover over it with the mouse, the menu folds with the different categories as it should, but if you move the mouse away, the folded out menu with categories stays there blocking the rest of the page! You will have to refresh or leave the page for the menu to disappear. Thought I will mention this bug here. Thanks!
