          try:
                    frame =3D  MainForm()
          except:
                    wx.Bell()
                    import traceback
                    import time
                    print traceback.format_exc()
                    mfile =3D AppName + '.log'
                    f =3D open(mfile, 'a')
                    f.write('\n')
                    tm =3D time.localtime()
                    print  str(time.strftime("%d-", tm)) +\
                    str(tm[1] - 1) +'-' + str(time.strftime("%Y %H:%M:%S",
tm)) + '\n'
                    traceback.print_exc(file =3D f)
                    f.close()
                    sys.exit(1)

This way, you get also an exception file you can read afterwards at you
leisure.
