Python - Code Completion

Hi,

I'm starting a new project &, whilst my previous project was VBScript, I thought I'd try setting the scripting language as Python.

I am having a problem with code completion (Ctrl+Space), though. If I reference another script (that exists in the same project), I can't access the variables/methods via code completion. Nothing pops up, which can get slightly infuriating, especially as VBScript handled it well.

VBScript

'USEUNIT test

Sub abc()
test.                      'brings up methods & variables. Ctrl + Space does the same job.
End Sub

Python

import test

def abc():
    test.              #does nothing. Ctrl + Space doesn't show any options either.

Am I doing something wrong? Is there a setting I haven't enabled? Any help would be appreciated.

Edit: I should point out that code completions does work with the application (identifying objects, methods etc). My issue is specific to imported scripts.
