[Radiance-general] rview window pop out black and exit

[Greg Ward]

Hi Ren,

I see nothing wrong with your command that I can see.  I would  
suspect something with your scene file, except if oconv ran OK then  
your scene must be alright.  It does seem likely that something is  
wrong with the X11 connection, but it's impossible to debug from here  
with no error messages or symptoms.  You can kill rvu with ^\ to get  
it to dump a core file (if enabled) and find out where it's stuck  
that way, but you have to know something about programming and your  
system configuration.  I know the former but not the latter, and I  
don't have access to your machine.  This is not a common problem.   
It's the first I've heard of it.

Anyone else have suggestions?

-Greg
