Background picture in Yosemite?

Hi There On pre-Yosemite systems, the background picture of a pkg appeared dimmed behind the text. In Yosemite, the background behind the text is blank (irony in a pan-transluscent OS?) Is there a way to get my dimmed background back? Thanks in advance Eric _______________________________________________ Do not post admin requests to the list. They will be ignored.
