Something strange is happening when I do this. If  I invoke 
IronPythonConsole interactively, I can import winforms.  But
something different happens when I execute a file.  For example, suppose 
ironPythonTest.py contains:

print 'Hello Iron Python!!'

import winforms

Possible bug 1: If I invoke IronPythonConsole like this:

C:\prog\IronPython-0.9.5\bin>IronPythonConsole ironPythonTest.py

I get:

Hello Iron Python!!

Unhandled Exception: No module named winforms

Possible bug 2: This generates the XP dialog: 'IronPythonConsole.exe has 
encountered a problem and needs to close.  We are sorry for the 

Possible bug 3: The same XP dialog appears if the file does not exist.

Possible bug 4: Without a workable -i option it is difficult to run 
IronPython from a batch file: the console goes away before it is possible to 
see whatever exception caused IronPython to exist.

Anyway, any ideas about what is causing IronPython not to be able to import 


P.S.  Here is a contents of the console illustrating this strange behavior:
