There is a known issue that the current beta version works with only 100% zoom level. Please check your browser and OS display zoom level and make it 100% to try it out before the fixed version is uploaded.

Speaking of zoom, it'd sure be nice if the keikai web site didn't kill zoom on the ipad. Pretty hard to see the screen shots, etc.
