Wouldn't it be nicer to fix twm, and send the changes back to the X
Consortium?  Backing store is pretty nice to reduce context switching... 
In X11R5/src/clients/twm/menus.c, there's the following: 
        case F_REFRESH:         {             XSetWindowAttributes
attributes;             unsigned long valuemask; 
            valuemask = (CWBackPixel | CWBackingStore | CWSaveUnder);   
         attributes.background_pixel = Scr->Black;            
attributes.backing_store = NotUseful;             attributes.save_under
= False;             w = XCreateWindow (dpy, Scr->Root, 0, 0,           
                    (unsigned int) Scr->MyDisplayWidth,                 
              (unsigned int) Scr->MyDisplayHeight,                      
         (unsigned int) 0,                               
CopyFromParent, (unsigned int) CopyFromParent,                          
     (Visual *) CopyFromParent, valuemask,                              
 &attributes);             XMapWindow (dpy, w);            
XDestroyWindow (dpy, w);             XFlush (dpy);         }        
break; 
        case F_WINREFRESH:         if (DeferExecution(context, func,
Scr->SelectCursor))             return TRUE; 
        if (context == C_ICON && tmp_win->icon_w)             w =
XCreateSimpleWindow(dpy, tmp_win->icon_w,                 0, 0, 9999,
9999, 0, Scr->Black, Scr->Black);         else             w =
XCreateSimpleWindow(dpy, tmp_win->frame,                 0, 0, 9999,
9999, 0, Scr->Black, Scr->Black); 
        XMapWindow(dpy, w);         XDestroyWindow(dpy, w);        
XFlush(dpy);         break; 
Why not change it to do what you want (Rob suggests explicitly sending
an expose event to the client (which may not work with clients like
xterm that don't accept client events, I think, whereas the current
trick of creating, mapping, and unmapping a window over the window to be
refreshed *will* work))?

Andrew on SPARC 
Hello, I have a problem installing Andrew on SPARC 10 workstations
running SunOS 4.1.3. The installation process successfully completed,
but every Andrew application that I start dies just after coming up. I
can see the window and text within it (for example, when I start help, I
can see the help text), but just after displaying the text, the window
disappears. Any suggestions or help? Thanks in advance,

InterViews does this nicely.  In the InterViews code, (almost) /no/ data
members are ever made public; they are all either private or protected,
with accessor functions just like O-O fans would expect. The way it
seems to be arranged is fairly sensible... If a given class doesn't make
sense without certain data members (e.g., size and position indicators
for a scrollbar), then those members are declared protected in an
appropriate base class.  Otherwise, they are private. 
Somewhere in /interviews.stanford.edu:/pub there is an explanation of
why these design choices were made.

because of IBM's 64k limit on TOC size.

OpenWindows crashes Andrew clients 
Hello, I have a question about Andrew and OpenWindows 3.0. I have
installed Andrew on our Sparc SunOS 4.1.3 cluster and it works fine,
when I use MacX or the MIT X11R5 X Server as displays, but whenever I
use my local X Server (OpenWindows 3.0), the application window shows up
and then disappeares with a segmentation fault. It's the same behaviour
for all Andrew clients, so this must be a general problem of Andrew
working with this special server. Does anybody have had similar problems
or effects? Maybe it's just a configuration problem, but I cannot find
it. Thankful for every hint,

<info-andrew+@ANDREW.CMU.EDU> Subject: Visit to Europe 
My paper "Andrew as a Multiparadigm Environment for Visual Languages"
has been accepted for presentation at the Visual Languages symposium in
Bergen, Norway, 24-27 August. 
After the symposium, I can visit a few sites in Europe to find out what
people are doing with the Andrew User Interface System and what needs
they may have.  As part of a visit, I would be prepared to give a talk
such as a discussion of future plans for Andrew or conversion of Andrew
applications to C++.  If you are interested in having me visit, please
send me email.  To make my travels financially feasible, the consortium
asks that your site contribute toward local expenses and travel from the
previous site.  (I prefer train travel if we can keep distances
reasonable.)

Huh?  This sounds like a bug in your version of messages.  The
MIME-Version: header is completely useless and should be ignored. It's
absence is certainly no reason to ignore a perfectly valid Content-Type:

MIME-Version is not present.

<nl> Hi,<nl> <nl> When <bold>messages </bold>first starts up, I gather
it reads the /var/spool/m= ail/<lt>userid> file (for sendmail), chops up

Absolutely.  Just try to generate it uniquely to avoid overwriting other
files!  There's a utility program $ANDREWDIR/etc/ams_genid that is
perfect for this purpose..... Return-path:

 To: Andrew Mailing List <info-andrew+@andrew.cmu.edu> Subject: ATK5.1 &
MacX problem 
Hello, 
I'm using ATK 5.1 and MacX 1.2 as display server. As soon as I try
loading a complex document (such as the ADEW-RefMan or arb) into ez, my
MacX crashes. From time to time it crashes while loading the document
and in other situations it keeps running for 5 seconds or even for some
minutes. MacX seems to crash somewhere when doing memory management. It
gets 5 MB and it never seems to run out of memory. I just get an
"unimplemented instruction" trap and have to reboot my Mac. The same
MacX did run without any major problem before we upgraded to ATK 5.1, no
other X-client caused my MacX to crash and ATK 5.1 does not cause our
sun workstations to crash either. Does anybody know this problem or
something similar. Maybe this is a known behaviour. 
Thanks Urs K"unzler (ukuenzle@iiic.ethz.ch) Return-path:

Thank you, thank you, thank you for doing this!!!  I use dark
backgrounds & light foregrounds, so by default all raised/lowered areas
are switched.  I've been able to fix a lot of it by setting
{Dialog,Scroll}Foreground to black and {Dialog,Scroll}Background to
white, but I've never found a way to fix, e.g, the On/Off buttons in
message options.  Is there a preferance I can use to fix these until
your updates are available?  If not, can you suggest a quick code fix?
