CFREPORT from CFC and IE returns blank page

I've got a report I built with report builder 7.0.2. Works great when viewing from Firefox. Returns a blank page when viewing from IE. Here's the catch: If I call the report from a cfm template using <CFREPORT>, it will display in IE, but only after clicking on what appears to be a blank flashpaper container. When returning the same report from a CFC, I get a blank HTML page (no flashpaper container or anything). All of these things work fine from Firefox. I thought the active content activation issue was fixed with 7.0.2. But the behavior has not changed since I updated both the report builder and my CF development server to 7.0.2. What gives?

Thanks,
Kris
