can't figure out error: module has no attribute...

Thanks for the reply.

you are indeed right, they were included from different places.
from C:\Python24\Lib and D:\mydir

But the strange thing is:
anywhere on C: the file from C:\Python24\Lib was included.
in D:\mydir the one from that directory
BUT: anywhere else on D: apparantly the one from D:\mydir was included
?!
I would expect it would come from c:\Python24\Lib.

Now I changed the files and of course I cannot reproduce it anymore.
Oh well, now it works.
