Hello, My Zope has given me "IO error" last few days. Here's a fragment from traceback: /---/ File D:\PROGRA~1\Intra\lib\python\tempfile.py, line 110, in mktemp File D:\PROGRA~1\Intra\lib\python\tempfile.py, line 68, in gettempdir /end/ As the disk where temporary files are to be put was full I set environment variables TEMP=D:\TEMP and TMP=D:\TEMP . Gettempdir suggests that it uses these variables. But no use. Any help would be helpful Platform is NT 4.0, Zope version is 2.3.2. Sven
