I've just done a quick test in ResTest and it does seem to be the case that
the Menu_SubMenu toolbox event is delivered repeatedly while the mouse
pointer is over the submenu arrow.

Looking at the toolbox source code reveals that this event is sent on
receipt of a MenuWarning Wimp message. So is the Wimp sending this message
repeatedly too? I've been using the Toolbox for so long I've forgotten how
the Wimp is meant to behave! More investigation is required.

Wimp 5.13, Toolbox 1.53, Menu 0.36 (ROOL versions).

[a short time later...]

It seems that the Wimp will keep sending MenuWarning messages until the
application opens the submenu. I suspect the problem is that the submenu
being opened is not the submenu specified in the parent menu's data.

Of course if the submenu was a Toolbox object, the Toolbox would correctly
fill in this data field.

I think the ultimate answer is to implement the submenu using the Toolbox.
