Unfortunately, most of my original msg was trimmed as the thread went
by.  The text in question is a popup that goes away when you try to go
on top of it.  Here is my original msg that makes this clear and
offers an example.

    Some popups have become invisible; I believe they have
    foreground=background=white.  Since I am using the color-theme
    package, I do not claim this is an emacs bug and I am not asking for a
    fix.

    My question is how do I find the name of this face.  For an example
    Start with emacs -Q
    and execute M-x customize RET

    Place mouse on ``Go to Group''

    Popup ``Create customization buffer for this group'' appears with
    perfectly fine black looking text on a light yellow background.

    But how do I find the name of this face (the one with black on yellow;
    not ``custom-link'', the face of ``Go to Group'').

    thanks,
