But I noticed that with "Main menu" disabled,
Sometimes when I expend the menu, "Tools" and "Help" are missing.
A restart fix the issue.
See screenshot:

Edit: I found out how to reproduce.
1. Uncheck main menu in view.
2. click on menu to expand it.
=> Working as expected.
3. go to tools > options > skin and switch to another skin. Close the options window.
4. Now click again on menu to expand it
=> Notice some elements are missing. ( see screenshot )
