How to tell if a command was called from a menu?

[Joost Kremers]

hi all,

is there a reliable way to tell in elisp if a command was called from a menu?
commands such as find-file and y-or-n-p behave differently when called from a
menu (they use a popup window instead of the minibuffer) but it seems that the
relevant check is done in the C part of the source...

TIA
