The sprite.js framework lets you create animations and games using sprites in an efficient way. The goal is to have common framework for Desktop and mobile browsers.
It could happen on the Nokia 5800 xpressmusic that if you close the browser while a download is running, that the next times every time you close it, you’ll get the message “…view interrupted downloads…”.
You can solve this issue by opening the browser, click on options->downloads. Then you’ll get the list of downloads. In the list you should see an “incomplete” download. You can resume or cancel it at all 🙂
