I've been seeing the same behaviour as Robert with the RAT.  I thought  
it likely had something to do with our unique configuration (ppc64's),  
and since it was a fairly low priority for us at the moment had put  
off investigating until the end of our semester.  Out of curiosity,  
what versions LON-CAPA are you running?
