Digital clock widget

Since upgrading to Fedora 16 I notice that the popup calendar in the digital clock widget has event information, including a new panel to the right with an event list. That would be nice, except it cannot be turned off. Plus I have no idea where the "event" are defined, or why some of the dates in the calendar have a box around them. Unchecking "Display Events" in the configuration dialog has no effect. My system is up to date at 4.7.4-1 Emmett
