You will likely find that there are some lag time when the data is loading/processing. I haven't yet optimized the code so it's slower than it will be in the release version. For this first beta, please be patient and let give it several seconds for the initial load. After I work out some of the major issues, I will begin to optimize the code to improve the performance.
Internet Explorer has a much slower JavaScript interpreter than the other browsers so this lag will be much more noticeable with IE.
