Don't use IronPython Studio - it is *very* unstable and uses IronPython 
1 which is years out of date.

Use IronPython Tools for Visual Studio 2010:

Basically you shouldn't use __slots__ because it causes problems like 
this... I think IronPython Studio creates classes with __slots__ when 
you use the windows forms designer. IronPython Tools doesn't have a 
winforms designer because it isn't really possible without horrible 
hacks. I recommend using the Visual Studio C# designer and then subclass 
the classes it generates from IronPython.
