MDX query designer behaving correctly in Reporting Services?

I've been working with the MDX query designer in Reporting Services 2005 (RTM Developer Edition) and have come across a behavior that does not seem correct.

I can build a report using the wizzard, preview it, deploy it, and all is good with the world. But if I so much as click on the Data tab in the report designer, the report becomes invalid.

Is this by design, or is there some other way to edit a report created with the MDX query designer?

This is apparently a known problem. I posted this to the Reporting Services forum as well and recieved an answer there. Heres the link:
