Control-C to interrupt is not working

[rburge]

My program will not respond to a ctrl-c interrupt to terminate it's execution. I have my guesses but not really sure why. The program has no GUI but it utilizes signals/slots so I have a QApplication object to get to a "main loop." I have different app which does put up a "main window" and it responds just fine to the ctrl-C. Is the lack of a window the problem?

Here is the main:

int main (int argc, char *argv[])
{
QApplication a(argc,argv);
ProcessMsgOperation pmo;
return a.exec;
}

int main (int argc, char *argv[])
{
QApplication a(argc,argv);
ProcessMsgOperation pmo;
return a.exec;
}

The ProcessMsgOperation sets up some socket connections and a timer. Either when a socket msg or a timer event occurs it reads from a database and then posts a message to a socket.

Thanks,
