Normally, when you hover over one of the dropdown menus on TMX’s ribbon (Maps, Mappacks, Records, etc.), you can hover over every button in the menu. However, if you hover your mouse over one of the text boxes / search bars (which reveals a label that restates what the text box is for, such as “Map Name”, “Tags / Styles”, “Author”), it will prevent you from being able to fully navigate the adjacent dropdown menu, causing the menu to disappear when moving the mouse over the position of the label.

Workarounds: Refreshing the page or navigating to a new page fixes this bug (until you hover the mouse over a text box on one of the affected pages again).
