In some configuration, where Emacs itself draws the tool bar (as
opposed to the toolkit doing that), the tool bar is a special kind of
window, and redisplay handles that window as well.  Your code should
refrain from producing the indicator in such windows.  I wrote in my
previous message how I propose to do that.
