x-windows + startup

[Daniel Katz]

My .login contains:

        xinit -- /usr/bin/X11/Xsgi -pseudo
                                gamma 2.2
                                xclock -g 200x200+180+40 -bg blue -fg white -hd grey &
                                xbiff -g +30+220 &
                                makemap

to startup x-windows and upon exiting, reset the screen.

My .xinitrc contains as its last line:

twm

so that exiting twm exits x-windows.

My problem is that occasionally (increasingly) when x-windows finishes, the
standard light blue background comes back, with the various chests, but the
x-window windows don't close.  In this situtation, certain windows under
x-windows opened as SG windows, with the lightning bolt, not as x windows.

Can anyone explain what might be happening?

Thanks
