We've created several new themes which extend the classic theme. We're setting the base variables and everything is looking great except the sliced images. Some of the images are being colored properly, but others (tools-sprites.gif in particular) are still the standard blue color. Is this a known issue, or should this be working? If it should be working, where would be the best place to look? The theme.html that's generated doesn't include tool sprites but everything except the triggers seem to be colored correctly on that page.
Here is an example screenshot from that page. The trigger coloring is an issue but the tool sprite is the most important to us.
