odd background image (possibly in css class "parent")

PS I'm using a (modified) theme pixture.
Possibly the css in pixture is defining classes in such a way that the images for bullets are overriding whatever VI is trying to set, and therefore VI images get repeated in the content area.

I found that in the collapsed view, i need to comment out parent-rtl.gif background in vocabindex-rtl.css, as well as parent.gif background in vocabindex.css (I don't know BOTH were getting active) to get the result I expect.

Still, the expanded view gives the down pointing arrow (repeated everywhere). I'm surprised that this only appeared when the others were commented out (in the screenshot I uploaded earlier, even when expanded, the parent-rtl.gif was showing as the background)
