Re: Tool bar buttons stay active too long

[Richard Stallman]

    I think all these flickerings are a ``feature'' of the redisplay that 
    Emacs decides to perform: each such redisplay first resets the buttons to 
    their inactive state, then raises them again.  This is based on a vague 
    recollection from reading the code long ago, though; Gerd, am I right 
    about this?

Why would redisplay raise the button again when the mouse is in the
menu bar, and therefore clearly not on the button?

(And why would moving the mouse in the menu bar, when no menu bar
menu is visible, cause a redisplay?)
