[Zope] ExternalEditor and Zope's gzip compression, in Windows

I just stumbled with a problem while working with both Zope's gzip compression and ExternalEditor: If you enable gzip in HTTPResponse.py, like this: use_HTTP_content_compression = 1 expect the problem that every time you click at the icon to launch the editor, Windows will start to ask for what to do with the to-download file. If you respond to open, then it will trigger the File Types dialog box, asking for the right app to open it. In other words, you'll be tempted to reinstall ExternalEditor. :) Any ideas of how to patch this? Thanks in advance, Ausum
