This section contains important information on testing the component in the Flash IDE while using its loading features.
When using external images or swfs for page content the pageFlipper component relies on the browser's cache so that it doesn't need to load these files multiple times. For each external file that you load as page content the component loads the file into one of several built-in movieclips. Upon initializing the pageFlipper loads the external file in one movieclip, and for the other movieclip it triggers the browser's cache so the user does not actually experience multiple loading of the same file.
The Flash IDE with the Simulate Download feature doesn't have a cache it can rely on and consequently when testing your file inside Flash you will need to wait for all files to be loaded before you see the result. This is experienced by the loading of about six files instead of the anticipated one.
Because the performance of the pageFlipper is considerably improved by your browser's cache it is recommended that you test your files in a browser to see the actual performance of your pages loading.
