This is a well-known problem. It is caused by the implementation of
Emacs menus on MS-Windows: we start a separate message loop for
handling the menu events, and this suspends the main event loop. When
blink-cursor-mode is ON, the timer causes the main event loop to turn
a notch, and then Emacs produces the help-echo for the menu item; but
without cursor blinking and no other sources of async input events,
that doesn't happen.
Patches to fix that are welcome.
