OK.

OK, but the Mail.Panel isn't changed. For example, suppose message 10
is selected in the Mail.Panel; the line for message 10 is in reverse
video. The message itself can be displayed or not. Mail.Show 13 will
leave the line for message 10 in the panel in reverse video.
What harm can occur if Gadgets.Update(obj) is omitted? Ie. the line list
and the displayed message are left inconsistent.
Thanks, ... Lyall E.
