See the screenshot below.
When I hover over menu item ‘Photos’, the 3 pull-down items (shown) appear. However, when I move the mouse pointer down to select a sub-menu item, they all disappear … unless I move the pointer down on the right-hand side of the ‘Photos’ item; then they stay, allowing a choice. This took me a while to discover and will be confusing and irritating for some site users. Do you know of this problem and can you suggest a solution? I am using an iMac and the problem occurs on both Chrome and Safari.
