Yeah, thanks, I got it! This problem is known (I was told it happens on Sparc Ultras only) and the update to 4.0.1c fixes it. Alex -- Alex Schuster Wonko@weird.cologne.de alex@pet.mpin-koeln.mpg.de

And you are running on a Sparc Ultra, right? Since FPS (our IDL reseller) don't really seem to be aware that this is a known problem and that there is a patch for it, I'll chip in with the answer. 4.0.1c fixes it. It took me more than a week of phone calls to FPS and to Sun to find this out, only to find out a) That IDL is officially not supported on any version of Solaris after 2.3. (!) b) They have a fix in the form of 4.0.1c anyway. It seems a rather inconsistent position to take, but who am I, a mere user to complain?
