Behavior

Here, you can customize the appearance of the Start menu and how menus respond to mouse events.

Under Menu speed, you can specify how long a menu waits to open when the mouse cursor is positioned over it. This also requires that the option Open menus automatically after indicated delay be selected. If you prefer, you can select the option Open menus only via mouse click.

Under Additional settings section, you can enable or disable dragging and dropping.
