Hi,
I see what you mean, thanks for pointing this out. Unfortunately the jscalendar javascript we are using there is not being maintained and has not been updated since IE 7 and 8 came along. At least it still works for picking dates even though it floats up the page more than we would like. I think I'm going to have to replace that date picker with a newer jquery one. I will try to look into it soon.
Best,
Joe
