In Windows if you click the Help dropdown, IDLE launches a help window as it should. The help contents are included in the installation.
In Linux, clicking Help launches a web browser, which is a perfectly good UI for viewing help. However, instead of loading a static HTML file from the disk like the Windows version does, it visits the doc directory on python.org over the internet. Is there any reason for that? It's noticably slower even over broadband, painful over dialup, and unusable if you're not connected to the net at all. -- http://mail.python.org/mailman/listinfo/python-list
