    Sorry, I indeed spoke too fast.  You reported a different pfoblem
    with disabling tooltips, one that involved a menu and code that
    displayed "TTTTT" in the echo area.

    Reading again your report, I have no idea what could cause it.

I just reread the other thread (subject "tooltip-mode disabled prevents
messagesin minibuffer"), and I think you were right the first time - I think
this is the same problem or something very similar (same cause?).

I'm surprised I forgot about my previous report (just a few weeks ago! -
CRS). I spent a lot of time yesterday discovering that tootip-mode was the
culprit. Had I remembered the other bug thread, I might have saved myself
some time.

    I guess you should fire me, then.

Hehe. Touche! In any case, _you_ are not unacceptable, Eli ;-).

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.

I see, from the other thread, BTW, that this bug on Windows is not
necessarily by design. Nick said this about the behavior on GNU/Linux:

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