Summary Report Not Showing

hi,

When I hover the cursor over the Hourly Total at the bottom, a pie chart pops up showing an small, but accurate daily graph. But when I actually click on the Hourly Total, the Pie Chart graphic will only display a summary of the last month. If I try to select any other range of dates, I only see the calendars, the pie chart graphic itself will not appear.

Using Firefox 3.0.2 with the Adblock plus extensin
(disabled for bubbletimer.com site but I figure worth mentioning.)

Thanks
