Hi Dave, With the suggestions you made above, I managed to solve the problems I reported, and now my paths work as expected. Thanks a lot, Ron. $ cat tmp.py #!/usr/bin/env python import sys import os print "sys.path:",sys.path print "sys.path[1]:",sys.path[1] print "os.listdir(sys.path[1]):",os.listdir(sys.path[1]) from ErrorManager.ErrorManager import ErrorManager $ python -u tmp.py sys.path: ['c:\\views\\cc_view\\TS_svm_ts_tool\\svm_ts_tool', 'c:\\views\\cc_view\\TS_svm_ts_tool\\SVMInspector\\lib', 'C:\\WINDOWS\\system32\\python26.zip', 'c:\\Python26\\DLLs', 'c:\\Python26\\lib', 'c:\\Python26\\lib\\plat-win', 'c:\\Python26\\lib\\lib-tk', 'c:\\Python26', 'c:\\Python26\\lib\\site-packages', 'c:\\Python26\\lib\\site-packages\\wx-2.8-msw-unicode'] sys.path[1]: c:\views\cc_view\TS_svm_ts_tool\SVMInspector\lib os.listdir(sys.path[1]): ['ConnectivityManager', 'ErrorManager', 'Utility'] $ echo $PYTHONPATH c:\views\cc_view\TS_svm_ts_tool\SVMInspector\lib\ $ echo $PYTHON_PATH c:\views\cc_view\TS_svm_ts_tool\SVMInspector\lib\
