To our great regret this is a problem that we have introduced with the latest version - Telerik Reporting Q3 2007 (v 2.0). We are currently working on the service pack that will fix this issue and will be ready in a couple of weeks. The only workaround we can suggest right now is to continue using the older version Q2 2007 SP1 (v 1.5.1) for a week or two until we are ready with the fix or stick with the trim.
Please excuse us for the inconvenience.
All the best,
the Telerik team
