Pie Chart value display by mouse-over malfunctions after flash upgrade.

A recent upgrade on the flash player to 10.1.102.64 is affecting the mouse-over function of some pie charts. The numerical value of the various parts of the pie chart is no longer displaying the values when users place the mouse over the pie chart. The mouse tip has to be positioned at the boarder of the chart to trigger the values to be displayed

Initial suggestions to remove the pie chart from the dashboard and rebuild it fixed this issue for a couple of dashboards a month ago. However this dashboard in question has 7 pie chart and the earlier fix does not solve the issue for the mouse hover error. Other suggestions to point the chart to different cells in the spreadsheet, run the dashboard and re-point it back to the initial cell; doesnu2019t fix this issue either.

Has anybody encountered this issue? Can someone explain why this particular dashboard and the few other which have been in production for over 6 months, suddenly have such issues? We are using Xcelsius 2008 Sp3 with no fix pack.
