You have a Microsoft SQL Server 2008 Reporting Services (SSRS 2008) report that uses Microsoft SQL Server 2008 Analysis Services (SSAS 2008) data sources.
You open a dataset, and then you open the query designer.
You click OK or Cancel in the query designer.
In this scenario, you may see the following error message appear:
Query Preparation is in Process. To cancel, press and hold CTRL+C for at least half a second.
This message window stays for a long time, even if you try to cancel it.
