Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I have a file foo.el, containing the single line

(y-or-n-p "hello")

I start emacs and load this file with the command 

emacs --no-site-file -q -l foo.el

and am prompted in the echo area/minibuffer with "hello(y or n) ".
After pressing one of 'y' or 'n', the text cursor starts flashing and
then the mouse pointer changes into the wristwatch-shaped 'wait'
cursor, and stays like that until I press C-g.  While the wait pointer
is active, the menus and toolbars do nothing when clicked on.

I do not see this behaviour if I replace the contents of foo.el with

(let ((last-nonmenu-event nil)) (y-or-n-p "foo"))

and repeat, but that involves popup dialog boxes, which I wish to avoid
for other reasons.

Any ideas?
