a possible problem with NeXT geomview

[roseman]

FYI  I had a very strange thing happen--it might be a bug but I  
havn't been able to repeat it. I send this for the information in  
case it might happen again, perhaps to someone else.
  

I was viewing a very large geom with the current version  
(geomview.scott).  I was moving some windows in front of the camera  
window and looking at what happens when one exposes the camera window  
again. (What happens is that the portion covered up is not updated  
until it is uncovered again thus one has a strange looking thing for  
a short time.  This is all standard stuff; there was no special  
reason to be doing this other than curiosity.)  Anyhow, some how what  
I did caused my Window Server to die leaving the following trail of  
error messages:
