Stop sign ignored while debugging linux pgm

[geneSmith <gene dot smith at sea dot siemens dot com>]

I have a program (written by someone else) that I need to look at with 
gdb. The program runs in a tight loop looking for a keypress and 
servicing tcp/ip events with select. When the program runs under insight 
it seems to remove all the oxygen from the insight gui in that the STOP 
button and other menus are ineffective. The program itself responds to 
the keypresses appropriately. Also, if a window covers the insight gui 
with the program running under its control it never get redrawn.

When the program runs stand-alone (with insight/gdb) it does not respond 
to ctrl-c. Do I possibly need some sort of SIGINT handler?

When I write my own program just looping forever on printf it responds 
to the STOP button (SIGINT) as expected and stops the program 
executation as I would expect. But the other program program does not.

Tks,
