I got KB816480 hotfix from Microsoft support, which fixed
the user-defined functions in dimension security definitions.
After I updated the hotfix, the OWC's pivot table crashes IE.
The situation is:

1, put owc's pivot table on MS Frontpage
2, set up New SQL Server Connection (Not Olap Cube)
3, select a table on "Pub" database
4, open the Field List on the pivot table
5, drag a field and drop on "Row Field" area
6, it crashes IE

Any idea or workaround?

Thanks,
Simon
