Um, make sure you compile with debug?

I have coded in Boo, which is very Python-like, and it will step
through the debugger just fine, so IP should do the same in theory.
But I've not used IP, so all I can give are generic "are you sure it's
plugged in?" type of suggestions.

Hmm, upon rereading your post, I see that you want the debugger to
step through a separate file that was executed using ExecuteFile.
Unless there are some debug options on ExecuteFile, I'd say your
chances are slim, since the file being executed is not really part of
the image being debugged.  You could also try explicitly invoking the
debugger from within the file that you are loading, using (this works
from Boo):

    System.Diagnostics.Debugger.Launch()
    System.Diagnostics.Debugger.Break()
