Cannot find the definition located in the file starts with underscore

[YEU-JIUN WANG]

I used WingIDE 3.1.2-1 under mac os x leopard. I found it cannot located the module or code located in the file start with underscore. For example, I use "Goto definition" in the function quickstart of "cherrypy.server.quickstart()" and it cannot find anything. The code actually located in  /usr/local/lib/python2.5/site-packages/cherrypy/_cpserver.py. The '/usr/local/lib/python2.5/site-packages' is in my PYTHONPATH already. Is there any idea how to solve this problem? Thanks!
