Description of problem:
This problem exists on both Enterprise Server 3.0 and Workstation
3.0. As previously mentioned, we're having a problem with the Motif
Window Manager (mwm) that is part of the openmotif-2.2.2-16 package.
There are two known problems with mwm. First, with the multiscreen
option enabled, the root menu only appears on the main screen

screens. Second, the window decorations are only correct on the main
screen. When a window (xterm, etc) is displayed on another screen
(not the main screen), there are no decorations. The attached images
show both a window on the main screen (correct) and a window on
another screen (incorrect).

(:0.1) nothing happens. When displaying an xterm onto the second
screen, the window is missing some of it's decorations. (see
attachments for example).
When using a right click on the root window of the second screen, the
mwm root menu should appear (works on main screen :0.0). When
displaying an xterm on the second screen, the window (and it's
decorations) should have the same appearance as windows on the main
