Thank you for the response but it seems to me that my problem are not the scripts any more. Even after I deleted the scripts (simple_tree and image_batches_error) the openbsd zope refuses to import the file. After 14 minutes mozilla informed me that the connection was refused when attempting to contact the server, zope (started with -D) shows the startup messages again and nothing was imported. Importing the same file with linux-zope succeeded after 16 minutes. tia Jens-Erik
