I am using v1.1 RC1 and have not modified my search_bar or search_bar_css templates but the arrow image on the Useful Searches button in the drop down quick search isn't showing.
I notice it is here on XF however I can't seem to find a reason why it isn't on my site
I have this problem as well...ever since 1.1 Beata1...I am using a custom style but also have not touched the search templates. If I click to show the background image the sprite does come up.
