I am using the RadPanelBar with the 2008 controls. I am using the Office2007 skin. I have changed the PanelBar.Office2007.css file to reduce the line height property to 20px on the .RadPanelBar_Office2007 .rpText class to make it smaller. However these changes are not being reflected on the page. If I inspect the loaded css when the page loads the old value is of 31px is still being used despite my changes. Any help?
