I am using Ubuntu 20.04 LTS with GNOME. When I go to the top bar and click on the Applications button, the applications menu opens up. However, while taking the mouse to my required application, it often travels over the Places button, which automatically opens the places menu. I do not want this to happen.
How do I configure it so that a menu opens only when I click on it and not when I hover my mouse?
PS: The hover to click problem is only there when another menu on the top bar is already open. If no menus are open, then hovering doesn't do anything and I do have to click to open it.
You can use the Disable Menu Switching extension.
