Opening a popup browser window of help sounds like a possibility. Some searches have found people who overlay, but it seems ugly to me. I have confirmed that the standard Silverlight 4 RichTextBox is so primitive that it's utterly useless as a way of displaying attractive formatted help text. The paragraph formatting has no Margin or Style properties so everything appears as a "slab" of text (like a paperback). I have previously used the WPF FlowDocument for making help and it works nicely, but none of that is in Silverlight. Greg
