IIS ASP Python 2.2 script works first time only

[Stephen Arndt]

Have a simple Python script hello.asp to create a web page which
displays current date and time.

<%@LANGUAGE="Python"%>
<% python script code here %>

After upgrading from Python 2.1 to 2.2 with win32all-146.exe my
hello.asp script runs first time OK. Then just a blank page is
displayed in IE browser window next Refresh or activation.  I am
running Python 2.2 on WindowsNT 4.0 server and IIS 4.0.

Any ideas why the hello.asp script would generate HTML code only the
first time a new hello.asp file is copied to the server?
