Re: Turning off tooltip-mode wipes out echo-area message

[Richard Stallman]

    Clearing the echo area randomly (or seemingly so), and thus losing
    application messages, is unacceptable for a good UI. And, possibly fixing
    some help-echo problem for menus is an insufficient reason for ending up
    with such behavior generally.

    He seems to be confirming that the behavior on GNU/Linux is correct and the
    behavior on Windows (losing messages) is a bug.

I would tend to agree, and I recommend that the people interested
in support for Windows fix this.
