In a legal development that may have long-term ramifications in the area of swiping, Caitlin Sanchez, the former voice of beloved kids' TV icon Dora The Explorer, has withdrawn a multimillion-dollar lawsuit against Nickelodeon, MTV, and Viacom.  The terms of the settlement were not disclosed.  Sanchez's suit claimed that the networks bound her to an "unconscionable" contract, precipitately fired her when she hit puberty, and tried to cheat her out of merchandising, residual fees, and other compensation from the hugely successful show.  Boots, Backpack, and Map could not be reached for comment.
