Some Yahoo SiteBuilder users have reported problems viewing the Flash animations in the content area, when added to the correct directory.
When you have created your Flash animation, you need to save it to your website directory. This directory can normally be found at C:/Program Files/Yahoo Site Builder/Yourwebsite.
If you saved the Flash animation in the correct directory, but can't see it displayed in the content area (as you can in figure 1), you need to close Yahoo SiteBuilder and restart it in order for the content to show up in the content area of Yahoo SiteBuilder.
