The FreeBSD 9.3R rxvt has been slightly dodgy, when I try to set window 
titles & prompts, that sometimes gives anomolies, both on kabini & when 
logged into remote machines. That *could* be the problem, I will try to 
chase that further. I will also try the !kabini login, although I use 
rxvt on all boxen & log into the other boxen from kabini under rxvt as 
well. I have only 1 monitor on my LAN, connected to kabini. I access all 
other boxen via SSH under rxvt/tcsh from kabini ....
