anyone gibe me some light? Thank you. :)

I am using python 2.5.1 on win2k with sp4

1. in iup.py, if I delete
[code]
_IupMap.argtypes= [
                   PTR_Ihandle,    #ih
                  ]
[/code]
then when I choose the menu "MDI-New", no MDI window come out. Why it
should be that?

2. for most of the time, I can only choose menu "MDI-New" 3~4 times,
then it crashes with this msg:
[msg]
Traceback (most recent call last):
  File "\loewis\25\python\Modules\_ctypes\callbacks.c", line 206, in
'calling callback function'
  File "mdisample_callback.py", line 372, in mdi_new IupShow(dlg)
  File "H:\my_project\iup4py\mini\iup\iup.py", line 434, in IupShow  ih,

    return _IupMainLoop()

[/msg]

sometimes this happens when I delete some other "???.argtypes=???"

and some time, it crashes with this msg:
