How does your program figure out where to find the standard library? Is it relying on the IRONPYTHONPATH environment variable to point to the location of the standard lib? If so, this is currently broken in pyc.py-generated executables and is a known bug: http://ironpython.codeplex.com/WorkItem

If you can get at the field, you call GetInvocationList() to return the subscribers. Getting at the field is not possible in all cases because it's not actually requir
