Need help with slightly modified Scroll SDK example

JT, for what it's worth, my aquarium screensaver never lets the roScreen go out of scope, and it fully refreshes itself (loads all new bitmaps, 30+) every 15 minutes without issue. It does, however, ensure that all other bitmaps and regions go completely out of scope before re-loading, which is why I suggested that might be the issue. It also uses the roCompositor for most of them, so it could be that it has better memory management built into it.
