SOLVED
After many months of calls and much frustration, I happened to get a godaddy rep who knew what the problem was. Apparently, when my site was created, there was supposed to be a plug-in added that added a GoDaddy menu at the top of the dashboard page. Under that menu there is a “Flush Cache” option which actually does flush the cache. The rep helped me install that plug-in. So now when I update one of the non-wordpress (my html) pages, I go in there and manually flush the cache. It works within 5 minutes.
Bob, I didn’t turn any caching on for these pages, but possibly GoDaddy did, though they aren’t WordPress pages and it’s a WordPress managed server, so these pages probably aren’t managed by any of their server stuff. I did go into my wp-admin and clear the cache in case it was affecting the refresh of these pages, but it didn’t do anything. Firefox did start showing the latest version about 48 hours after it had been uploaded to my site. IE shows it immediately, Chrome a bit later, and Firefox at some point in the future.
