Hello guys,

 From a standard install of IronPython 2.0.1 on Vista 64, calling dir on 
System.ArgIterator blows up:

C:\compile>"C:\Program Files (x86)\IronPython 2.0.1\ipy.exe" -D 
IronPython 2.0 ( on .NET 2.0.50727.3074
Type "help", "copyright", "credits" or "license" for more information.
 >>> from System import ArgIterator
 >>> dir(ArgIterator)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
SystemError: An attempt was made to load a program with an incorrect 
format. (Ex
ception from HRESULT: 0x8007000B)
