FIXED: Calendar pop-up Description populates blank Descriptions?

Is anyone else seeing the Calendar pop-up Description of one event take over the Description boxes of other events in the same month? What happens is this: I scroll over an event, and the Description pops up. If I then scroll to another event, the summary for the first one I looked at shows up there. This always happens when the second Description box is empty. This is for an AHG Troop in case it makes a difference.

Thanks for any help you can give me on how to prevent this.
