    1): Although I can't seem to find it in the Intuition Manual, =RJ Mical=,
    Intuition author, takes a firm stand that menus *must* have at least
    one item.  Please direct philosophical comments to him.  The status of
    this in future intuition releases has not been finalized, but in the
    meantime you must not set a menu strip with a menu having no items.

    2): By popular demand, (i.e., demand including that from the ever-popular
    never-mellow-mike) I'm posting another thing about shared IDCMP ports.
    Because this is thursday, I am throwing in, absolutely free, some
    valuable insight into using MENUVERIFY, SIZEVERIFY, and REQVERIFY.

    Please send me questions/problems regarding this.

    Watch that news, guys/gals, for these valuable things, and as always...

	go wild.
