X locks up

I have been having trouble with my system.  For some reason,
I've only
noticed it recently, but nothing has been updated on the
system.

What happens is that sometimes (amazingly frequently) when I
have open
office running on my right screen and I click
"File", the displays will
freeze.  The system is still running, because I can get in
from one of
my terminals.  I check and X is consuming 100% of one
processor.

I can kill openoffice and ctwm (my window manager) reasily,
but I have
to use -9 option to kill to get X to die.  Even after that,
though, the
video and keyboard are still locked.  The only way I know of
to get them
back is to restart the system.

IIRC, it only happens when OOo is on the right screen, but I
can start
oowriter2, put it on the right screen, and click file and it
won't
always lock things up.

System info:
openoffice-bin-2.1.0
xorg-x11-7.1
xorg-server-1.1.1-r4 (VIDEO_CARDS="mga",
INPUT_DEVICES="keyboard mouse")
libXinerama-1.0.1
ctwm-3.7
Video card: Matrox G450
System starts up to a CLI login, not XDM

Anyone have any clue as to what is going on here?  Is there
a way I can
release the hold on my keyboard and/or display so that I can
just get to
the console so that I can reissue "startx"?

try removing the card and put it in its slot again

try a different PSU

check your board for 'strange' caps.

yes, that way is known as 'sysrq keys'. Please 
read /usr/src/linux/Documentation/sysrq.txt
