Cannot use separator bar as menu name for this control (Error 395)

A Menu caption that has submenus can't be changed to a separator bar. This error has the following causes and solutions:

• At either design time or run time, you tried to change the Caption property on a parent or top-level Menu to a separator bar.

  Remove the dash character from the Caption text box in the Menu Editor dialog or the Caption property in the Properties window, or change the reference in your code.

• At run time, you tried to change the Caption property on a Menu which is checked, disabled, or has a shortcut key to a separator bar.

  Change the reference in your code or read the setting of the Checked or Enabled properties before trying to change the Caption property. You can't read the setting of the Shortcut property at run time.
