I summarise our time recording data (11000 rows, 1.2MB) with a simple pivot
table. On 3 separate occasions with 3 different cuts of the data it has
corrupted.

Symptoms:
All OK when you create the pivot table and save as .xlsx. But when you next
open the file you get a message: "Excel found unreadable content". Recovery
removes the pivot table!
Looks like http://support.microsoft.com/kb/929766/en-us but I can't see
where to remove references to Current Time Member as it advises. I am not
connected to SSAS though the data came from SRS
I do add Calculated Fields to the Pivot table - and would like to keep doing
so

Is this the known bug or a new one?
