CMS Can't configure widget
 

Since upgrading from 4.03 to 4.04, my latest posts are not showing up in the widget. I tried to configure the widget, but get a momentary black screen, then it flashes back to the widget list screen.

I tried to deleting the widget, the recreating, but it does the same thing upon configuration.

I have tried in Firefox, IE8, and Safari (thinking it was a browser issue) and on different computers so I am stumped. Hope someone can help because my site now sucks.
