Yes, using motif:
Window System:
Compiling in support for the X window system:
- X Windows headers location: /usr/X11R6/include
- X Windows libraries location: /usr/X11R6/lib
- Handling WM_COMMAND properly.
Using Lucid menubars.
Using Lucid scrollbars.
Using Motif dialog boxes.
Using Motif native widgets.

I'll try this next.

no, its ":0.0". I also have an active vnc server session running on this
machine as ":1.0", but I don't see how that could be involved....
I was able to easily repeat the problem on an unoptimized XEmacs
by doing the following:
open a large text file (75,000 lines, 5+meg)
C-x h M-= -- mark entire buffer, then count lines.
xemacs appears hung...
move cursor around between frames, focus isn't working right
C-g a few times. BadWindow msg comes out and exit() is called....
