I've been encountering issues with "undimming" a Dojo Dijit dialog. Even though I am using the appropriate calls, there are instances where parts of the page remain dimmed. I can still scroll through the windows and access the undimmed sections. Is there a way to forcefully undim the entire page or its DOM equivalent? Additionally, is it possible to instruct Dijit.Dialog to "dim" the entire page instead of just the portion currently in view?
