This was a good lead. Not a shell script, but I was sometimes calling john via sudo, because the working directory for some jobs was only readable by root. This explains why it was intermittent for me. Neither invoking a full shell (sudo sh, sudo bash, etc.) nor "su -" exhibit the symptom; just "sudo john [...]". Why would running john via sudo make key-press status updates not appear? My not-so-secret X power appears to be finding weird use cases that most people never trigger ... Royce
