The problem in signal 2 (SIGINT) I fixed with a kluge in the version of visual.c I posted a couple of months ago. The problem with Signal 1 (SIGHUP) is still outstanding. When vnews receives a hangup signal instead of exiting it goes into an endless loop, eating up cpu time. Maybe that is fixed in 4.2. The SIGHUP signal is handled in code shared with readnews. Under 4.1 readnews did not have to worry about this issue because it used the old signal mechanism. If the 4.2 readnews has not been changed it will now also have this bug. I will know in a few days when I try to bring up 4.2 here. -- Bill Sebok Princeton University, Astrophysics {allegra,akgua,burl,cbosgd,decvax,ihnp4,kpno,princeton,vax135}!astrovax!wls
