Advertising software maker 180solutions has <A HREF="http://news.zdnet.com/2100-1009_22-6033054.html?tag=zdnn.alert">dropped its lawsuit</A> against Zone Labs, a move that comes two months after it accused the Web security company of unfairly classifying its software as "high risk." Two months ago, 180solutions filed suit to try to force Zone Labs to change the classification and the wording of its warnings. Zone Labs sent prompts that told some customers that 180solution's software monitored their keystrokes and mouse movements. Sean Sundwall, a spokesman for 180solutions, suggested that the lawsuit served its purpose, as Zone Labs has since altered the classification of 180solutions' software from "high risk" to "suspicious."
