This is because Archetypes is supposed to be in a package named Products 
and not directly in the Python path.  With the above setting in the 
project properties, Wing should find the definition of DisplayList if 
'from Archetypes.utils import DisplayList', but that might not work at 
runtime.

Part of the issue here is that Zope plays tricks (for good reasons) to 
get files that appear in both Products directories to be in one Python 
package.  In unmodified Python, the first directory on sys.path that 
contains an __init__.py directory is the package directory and only 
modules in that directory are in the path.  Wing uses this definition of 
sys.path when it analyzes source code.  We plan on adding support for 
the Zope instance directories in the future.

I don't know why this seemed to work in Wing 1.1.
