Hi Dave,

My Python is the Windows Python (I need this for wxPython):

$ ls -ls `which python`
1 lrwxrwxrwx 1 rbarak mkgroup-l-d 31 Mar  4 14:02 /usr/bin/python -> /cygdrive/c/Python26/python.exe

Here's a demo script:

#!/usr/bin/env python

import sys
print "\n",sys.path,"\n"

from ErrorManager.ErrorManager import ErrorManager

And it's run produces:

$ python -u  tmp.py

['c:\\views\\cc_view\\TS_svm_ts_tool\\svm_ts_tool', '.:\\cygdrive\\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']

Traceback (most recent call last):
  File "tmp.py", line 6, in <module>
    from ErrorManager.ErrorManager import ErrorManager
ImportError: No module named ErrorManager.ErrorManager

$ ls -ls /cygdrive/c/views/cc_view/TS_svm_ts_tool/SVMInspector/lib/ErrorManager/ErrorManager.py
4 -rwxr-xr-x 1 rbarak ???????? 1843 Sep 21 19:16 /cygdrive/c/views/cc_view/TS_svm_ts_tool/SVMInspector/lib/ErrorManager/ErrorManager.py

$ grep ErrorManager  /cygdrive/c/views/cc_view/TS_svm_ts_tool/SVMInspector/lib/
ErrorManager/ErrorManager.py
class ErrorManager:

$ echo $PYTHONPATH
.:/cygdrive/c/views/cc_view/TS_svm_ts_tool/SVMInspector/lib/

Please let me know if the above is enough, or you'd like to see the results from a Windows' DOS window.

Thanks,
Ron.
