We have recently started using K2 for content and have two issues:
1. When viewing an item the Rate This doesn't display or work properly. It allows you to vote but has little double arrows over the stars and doesn't maintain the rating in the stars (it does show when you edit the item, but not the stars.
2. When editing or adding an item from the front end it doesn't show the tabs properly for save or cancel, nor does it for the Content and Image tabs.
On another formatting issue, the home page displays the titles with 'extra space,' in the titles, like paragraph formatting is different (using article section blog layout.) This only happens in IE, not Chrome or Firefox.
