Conference bulova::decw_jan-89_to_nov-90

    I believe there is an "auto_unmanage" resource that may default to
    being true.  The resource is listed in the low-level widget creation
    call, but I couldn't find it in the UIL reference manual.
    
    You may need to add something like
    
      value auto_unmanage : argument ('autoUnmanage', boolean);
    
    in your UIL file and then use it as a resource when you define this
    particular dialog box.
    

auto_unmanage is true by default for popup dialog boxes.  See page B-30 in the
UIL manual.

--PSW

	In keeping with the spirit of reducing the number of topics in this
conference, I'll put this here since it's about popup dialog boxes.

	Someone doing a PMAX port noted that when he defined a popup dialog box
as the child of a widget he had some problems.  Essentially, what he wants is
to define ONE popup dialog box instance and then have that one instance popup
when MB2 is pressed in any of 4 main window widgets his application uses.

	Can he do this with one widget instance or does he need to define one
instance for each window?  The dialog box and its children are identical in all
cases.

	Also noted that when he bound the popup to MB2 that he lost MB2
functionality on the scroll bar associated with the window.  When he pressed
MB2 while over the scroll bar, he got the popup instead of the default MB2
behaviour for scroll bars.

Thanks

Same title, different problem.  

When MANAGEing a UIL popup_attached_db, I get the following:

  Error in DWT:MANAGE-CHILD: Attempt to modify system vector, T or NIL.

What does this mean?

Background:  This occurred in VAX LISP 3.0.
The FETCH WIDGET performed successfully.  I was able to manipulate some of the
children's resources, though I never managed nor mapped the popup.

The full UIL description follows:
