For many years we had used LUCID scrollbars that didn't
work very well (so nobody was really using them).  Recently,
we switched to the Motif scrollbars that are much nicer.
However, there is an annoying menubar issue.  Often X-windows
emacs will freeze after emitting this on stderr when launched
from the command line...
$ emacs-29.2 &
$ Warning:
    Name: menubar
    Class: XmRowColumn
    XtGrabPointer failed.
Usually, this will lock-up emacs and you have to kill it from
the window manager which seems to be the only option available.
When there are unsaved files, you still get a prompt for that
so it is not a crash, but just very annoying.
However, I realized that this bug/feature had already been
addressed for LUCID scrollbars in lwlib/xlwmenu.c but that code
is inactive for Motif.  So the simple solution is to uncomment
this block from lines 2906 to 2913 for Motif as well...
//#ifdef emacs
  if (x_had_errors_p (display))
    {
      pointer_grabbed = 0;
      XtUngrabPointer ((Widget)mw, event->time);
    }
  x_uncatch_errors ();
//#endif

The macro emacs is always defined, and this block of code relies on the
presence of an earlier call to x_catch_errors, which would not have been
satisified if this "#ifdef emacs" was inactive.  Therefore, something
else is at work here.

Hi Po:

I didn’t realize that emacs is always defined (so what’s the point ;o)

How would I go about debugging this issue?  I have been trying to
figure this out for months.  Thanks

At some time it was intended that the Lucid widget library could be
integrated into other programs (as the company who wrote it many moons
ago did put into practice), but that has long since been neither a
feature of any importance to us nor possible.

Please start by recounting what immediately precedes the appearance of
such an error message, in your experience.

Ping! Rodney, could you please provide the details requested by Po Lu,
so we could make some progress here?

We run emacs on a Linux server and display it on Macs and PCs
with X-windows.  We have about 30 users but not everyone is
using emacs all of the time.

The worst part of the problem shows this warning when emacs
freezes after emitting this on stderr when launched
from the command line...
$ emacs-29.2 &
$ Warning:
    Name: menubar
    Class: XmRowColumn
    XtGrabPointer failed.
If launched from the window manager, you can still get the freeze,
but you obviously won’t see the warning.  So as the warning says,
it is an attempt to activate the menubar (for me, its Files or Buffers).
But this doesn’t happen every time.  What does happen every time
is that clicking on the menubar leads to a 10 to 20s pause (but it
really seems longer).  Sometimes you don’t realize that nothing is
happening and you continue clicking or typing.  And occasionally,
this will lock-up emacs (emit the warning) and you have to kill it from

the window manager which seems to be the only option available.

When there are unsaved files, you still get a prompt for that

so it is not a crash, but this is very annoying since you have

to restart emacs (and of the course the menubar lag).

Perhaps, this has over-loaded some event handler?
But you can exit normally.  Hopefully that helps.

I thought that I explained this problem in this report, and that Rodney
has also found a workaround to his liking.  This behavior is network
latency at work, compounded by certain deficiencies in the toolkit's
implementation, which is not an issue that we are in any position to
address.

Thanks, closing.
