SSRS 2008R2: Set initial drill down to expanded with (-) sign problem.

The two forum threads below report the same fix to this issue.  However, when i tried it in 2008 R2, it did not open the report in expanded fashion it only changed the initial "+" sign to a "-" sign.

"Open the property grid, select the textbox that has the toggle image, and you will see a property named InitialToggleState under the Visibility group. It should be False if the toggled group is collapsed by default, or True if the toggled group is expanded by default."

This does not work.

So how do you get it to open expanded?
