I have run into a strange run-time error message several times while developing
XView applications.  Under arcane circumstances I get the following:
XView Warning: obj 0x### invalid object(embedding seal incorrect) ...
or something like that.  I have not found any clear pattern to when I get it,
I have usually been able to eliminate it by moving some code from one place
to another.  Generally the code tries to change display attributes of an
XView object.  Unfortunately, I am doing this mostly by guesswork, since I
do not really know what conditions cause an embedding seal violation.

So, what does this mean, and what makes it occur?
[I have looked in TFM and could not find any error messages documented]

This error is occuring most persistantly in code in which I am trying to
dynamically change the active choices in a menu according to the cursor
position when the SELECT button was pressed.  I have tried all sorts of
organizations for the code, and the only one which did not die displaying
the menu was when I disabled the code to change the selectability of the
menu items.  Unfortunately, the program then dies if the user selects an
invalid menu item!

So how do I do this?
About the only thing I have not tried is using a MENU_GEN_PROC, since I
consider it inadequately documented in all existing XView documentation.
And if this *is* how to do it, how do I use a MENU_GEN_PROC to change the
attributes of a pop-up menu (as opposed to a pull-right or pull-down menu)?
