Edit 2013 Aug 26: This may have recently been solved in core. Anyone know?
Have you ever had the contextual links overlap? Here's a quick fix. It probably works for other themes but, for the record, I did this on the Poultry theme, a Zen subtheme (used in RedHen CRM).
add this css:
.contextual-links-region .contextual-links-region { top: 20px; }
