The issue here is w/ the timing of starting up the Winforms thread and returning control back to your module. This will be fixed in beta 6, but you can make the change to winforms.py yourself by adding the marked 4 lines:
from System.Drawing import Size from System.Windows.Forms import Form, Application from System.Threading import Thread from IronPython.Runtime import CallTarget0 from System.Threading import AutoResetEvent # add me import IronPython are = AutoResetEvent(False) # add me def thread_proc(): global dispatcher dispatcher = Form(Size = Size(0,0)) dispatcher.Show() dispatcher.Hide() are.Set() # add me Application.Run() def callback(code): if code: dispatcher.Invoke(CallTarget0(code)) else: Application.Exit() t = Thread(thread_proc) t.Start() are.WaitOne() # add me IronPython.Hosting.PythonEngine.ExecWrapper = callback Do you want to help develop Dynamic languages on CLR?

This one's quite a weird one. I've written a small .py file (attached) that when loading has some strange errors. If I type the code in by hand, then it runs no problems. If i drag the file over IronPythonConsole.exe, then it brings up the "Submit an error report" message. If i double click the file (so it loads with IronPythonConsole.exe) it runs fine (although the console window doesn't disappear when the form closes), and if I open IronPythonConsole and import the file, it prints out the following. 1 2 3 Traceback (most recent call last): File H:\IronPython-1.0-Beta5\sample.py, line 6, in Initialize AttributeError: 'Form' object has no attribute 'ShowDialog' Hope that's enough detail. The winforms.py file that I'm using is the one in the templates directory, but I've copied it to the lib directory.
