Check the Cache setting on your browser. Mahe sure it specifies "Once per session" and not "Every time" If using Netscape, you would choose Edit, Preferences, and click the + sign to expand the Advanced options. Then, click Cache and check or change your settings. I don't know whether you need to restart the browser after changing the setting?
Hope this helps. There is a lot of messages on this board to download compared with other boards.
