Yes, I've seen this problem with 18.55 on a local Ultrix 3.1 vax and various sparc machines running both 4.0.3 and 4.1, where the DISPLAY device is distant (Livermore). Our traces look the same. It's a problem because the emacs process just eats up CPU time. Any hope that this'll be gone in v19? stephen pope advanced computing lab, lanl scp@acl.lanl.gov
