I am having a problem with an implementation of the X11R4 server.  On
our 68030 box I have compiled with gcc a MFB server using Sun's BW
code.  My X11R4 source is up to patch level 18.

While using the server parts of windows may become `stuck' in the
foreground and obstruct any other objects (that is, it is stuck in the
`super' foreground and no client will be able to write over it).
This obstruction will stay even if client that created the window is
moved or killed.  The only way I have found to remove the obstruction
is to reset the server.

This `ghosting' as I will call it stays even when the screen saver
turns on.

If a window is move to region of the obstruction events will go to the
window moved window NOT the window that caused the obstruction.

I can usually make this problem appear by using olwm (from AT&T) and
click and hold with the right mouse button on the menu bar and (when
the menu comes up) click on ``Full size'' option with the left mouse
button (while the right mouse button is still held down).  At this
point the xterm with grow to full screen size but the bottem part of
the old window will be stuck.

This also happens when using twm but I haven't been able to re-create
it at will in this case.

I have investigated this problem a bit and nothing seems out of the
ordinary to my admittedly naive eye.

Has anyone seen this or a similar problem?  Any pointers would be
aprecieated.

Pax, Keith
