Allow Menu to Instantly Return without Selection

[0StackOverflow0]

If dev passes GDISP for bS argument, then loop breaks and control is returned instantly without selection process.

This enables similar behavior to Gadgets like GButton.

Ultimately, this allows the dev to compose a screen with multiple visible controls, without the Menu needing to be the initial focus.

Very late looking at this. Im not sure what you mean, you can press ESC to exit the menu. Stacking menus (ie: submenus means you have to press ESC at each level). Can you provide a more specific example of the issue?

I'll try to demo what I meant soon.
The rough description from memory is I created a title menu (like File, Edit, Help), and then a windowed menu.
The windowed Menu is meant to hold focus, and escapes to the Title menu.
If I recall, before this change, the Title menu could be created, but would require a User action to then compose the Windowed Menu.
The idea was to pre-stack windows before user interaction.
