I am in the process of upgrading my Report Server projects from 2005
to 2008. These reports use an Analysis Services data source and have
queries that are anywhere from 20 to 100 lines of MDX. After
upgrading a report, when I open or save a dataset in the Query
Designer, it takes up to 20 seconds. In 2005, this would happen
almost instantly. Anyone else experiencing this?

Thanks,
Mitch
