Finally got an epiphany after pulling my hair out trying to figure out why my Dead Tracks images' corners weren't rounding when my other sites' images were.
Was using the same @#$%^& code, the @#$%^&* CSS. GRRRRRRR!
Finally realized I had those images set for 3% padding elsewhere in the CSS.
Padding big NO-NO with border-radius. Border-radius no like padding!
Changed the @#$%^&* padding to margin and now everything is joyful in CSS land.
