I've seen the update and applied it .. however, its not showing the full width. The width is there for it, in the widget, as far as I can tell, but the graphic itself just seems cut off.
The "preview" on the left is what I'm seeing on my site, and I'm assuming on the right is what should be showing.
As you can see ... there's more width for it to use, and the corners are rounded so it's not the width of the widget itself that is clipping it.
The new raid in WoW is out next week .. and the Raid Progression widget doesn't appear to be updated for the new bosses. Is this is the works?
