Make sure the command line in your .twmrc which launches the client
(xterm in this case) is suffixed with "&".  twm doesn't automatically
background the processes it starts, which causes problems when 
windows open:  The client must negotiate some parameters with the 
window manager, but the window manager is stuck in a wait() or 
somesuch and can't answer the negotiation attmepts.

     but it hurt when I walked.                          Mark Newton
