On the systems to which I have access (which include GNU/Linux and
MS-Windows), the mode line does not update as long as the menu is
open.  It only gets updated when I exit the menu, e.g., with C-g.
Needless to say, the menu does not disappear nor appears broken.

What terminal emulator do you use?  Do you see some of the problems
described in bug#17497?

Can you show a recipe for this starting from "emacs -Q"?

Thanks.
