Hi all,


	I have a program built using Unidraw which is uses a 
	set of routines for interprocess communication. These 
	routines work fine when in a non Unidraw application,
	but the parts which involve the Unidraw appliaction 
	receiving data don't seem to work.

	On further exploration, i found that our routines needed
	Interrupts to work, so I checked these out. It seems that
	Unidraw takes over the Interrupts before anything else is done,
	i.e even before the main function ???

	Any hints from anyone 
	Anthony




	Here is most of my code

	IE. This works fine


	#include <stream.h>
	#include <signal.h>
	#include <stdlib.h>

	/*****************************************************************************/
	void myinthandle0(int sig,int code,struct sigcontext *scp, char* addr)
	{
		cerr << "#######Interupt......" << endl;
	}	

	int main (int argc, char** argv) {

        cerr << "Turning signal #2 off...." << endl;
        signal(SIGTERM,SIG_IGN);
        sleep(5);
        cerr << "On......." << endl;
        signal(SIGTERM,myinthandle0);
        sleep(5);
	} 


	BUT This ignores my handler.........??????

#include "nedcatalog.h"
#include "nedcreator.h"
#include "neded.h"

void myinthandle0(int sig,int code,struct sigcontext *scp, char* addr)

  NedCreator creator;

  cerr << "Turning signal #2 off...." << endl;

  sleep(5);
  cerr << "On......." << endl;
  signal(SIGTERM,myinthandle0);
  sleep(5);

  Unidraw* unidraw = new Unidraw(
      new NedCatalog("ned", &creator), argc, argv, options, properties
  );

  if (argc > 2) {
    cerr << "Usage: " << argv[0] << " [file]" << "\n";
    exit_status = 1;

  } else {

    const char* initial_file = (argc == 2) ? argv[1] : nil;
    NedEditor* ed = new NedEditor(initial_file);

    ToolPalette* ted = new ToolPalette(ed);

    unidraw->Open(ted);
    unidraw->Open(ed);
