Apparently, it is "just a bug", because I have tried everything I could
think of, and nothing seems to make IDL recognize that the menu has been
realized. I've tried unmapping the menu, adding the new entry, and
remapping it. Then I tried desensitizing the menu, adding the new
entry, and resensitizing it. I tried both of the above, along with
re-realizing the entire menu, then the entire GUI. None of these
helped.
I went to read the on-line help, and noticed an indication that a widget
placed into an already-realized hierarchy will be immediately realized.
I am in fact seeing exactly that (since I can click the button), but
apparently, the Solaris version of IDL fails to see that.
As a reminder, though, it does work fine on the PC (both 5.4 and 5.5),
and on Solaris, v5.4.
I'm at the point of considering alternatives to my design.

I've no idea WHY you get the message, but surely
you have been working with computers long enough
not to be surprised by something like this. :-)
Let's just say that people who write operating
system software have a sense of humor and leave
it at that.
I expect you *could* try realizing the button after
you created it:
new = Widget_Button(parent, $
Value='Am I realized?',event_pro='testRealized')
Widget_control, new, /Realize
Let us know.
Cheers,
David

RSI has acknowledged that this* is an IDL bug and will fix it in IDL
5.6.
-David S.
* Phillip David's original description:
The code adds menu items when the user selects certain functions, then
selects the new button by sending a fake selection event to it using
Widget_Control, send_event. However, when I attempt to run this code
under IDL 5.5, I'm getting a warning message about the menu being
unrealized.
