Actually, the issue may not be cygwin per se, but perhaps changes in X. Anyway, I had typically put this in my .twmrc file:
"q" = s | c : all : f.quit The intention was for control-shift-Q typed anywhere to cause twm to finish. I also have a menu item: "quit" f.quit If I exit using the menu item, everything is ok, but if I use the c-s-Q method, I get a seg fault in X. I attach the log file. I have other twm questions/issues, but it's probably best to put them in a different email :-) ... Eliot Moss
