Exception in DataSet Visualizer for datasets with multiple tables - vs 2008 pro

In Visual Studio 2008 pro (Version 9.0.30729.1 SP) I always get an error when trying to use dataset visualizer on datasets with multiple tables. The first table is fine, when I select any other table I get the message below. It's easy to get around by adding a watch on each table, but still annoying. Anyone else have trouble with this? 

************** Exception Text **************
System.NullReferenceException: Object reference not set to an instance of an object.

I'm using the (free) RightHand DataSet Visualizer now. Doesn't have this issue and is a lot more powerful.
