[Zope] import * confusion in external methods

[Chui Tey]

After installing mxODBC and mxDateTime in Zope/lib/odbc and 
Zope/lib/DateTime, I tried to do this from the 
monitor_client_win32.py:

>>>import ODBC
>>>c = ODBC.Windows.Connect('dsn','Admin','')
------
1999-09-27T07:51:48 PROBLEM(100) ZServer 
exceptions.AttributeError Connect [C:\Program 
Files\WebGalah\ZServer\medusa\monitor.py|found_terminator|119] 
[<secure_monitor_channel connected 127.0.0.1:1764 at b148f0>|?|1]
Traceback (innermost last):
  File "C:\Program Files\WebGalah\ZServer\medusa\monitor.py", 
line 119, in found _terminator
    exec co in self.local_env
  File "<secure_monitor_channel connected 127.0.0.1:1764 at b148f0>",
line 1, in  ?
AttributeError: Connect

Looking at the attributes of ODBC.Windows reveals :
>>> dir (ODBC.Windows)
------
1999-09-27T07:54:29 INFO(0) ZServer ['__builtins__', '__doc__',
'__file__', '__n
ame__', '__path__']
['__builtins__', '__doc__', '__file__', '__name__', '__path__']

Running dir() on a Python interpreter, the Connect method is visible.
>>> dir (ODBC.Windows)
['BIGINT', 'BINARY', 'BIND_USING_PYTHONTYPE', 'BIND_USING_SQLTYPE',
'BIT', 'CHAR', 'Connect', 'DATE', 'DATETIME_DATETIMEFORMAT', 'DECIMAL',

'connect', 'error', 'errorclass', 'mxODBC', 'mxODBCType',

What is happening here? Why does Zope hide some of the module's
attributes?
