So I installed both posts and comments indexers and network activated them prior to network activating Live Stream widget.
I added two widgets one for content type comments and the other for posts.
When a user ads a post to their MU site/blog it shows up in the widget setup for comments and when a user adds a comment it doesn't show up unless the page is refreshed but it is showing up in the widget setup for comments.
Both widgets are set for "Live - load new content via AJAX. No Scrolling"
Under What content to show: I have tried all three options as well.
Is this a bug or something that I am doing wrong?
