Found that program had termios flag ISIG forced off. If left on can now 
at least do ctrl-c in program's xterm and cause insight to halt which is 
good. However, STOP button (and other menu items in insight) still 
disabled while program is running. Would be nice if STOP button worked 
but having ctrl-c respond is next best thing.
