Microsoft to Ease Browser Switch

Microsoft, bowing to federal government demands, will make it easier for computer users to substitute rival Web browsers for its Internet Explorer, sources said. The revisions address charges from competitors that Microsoft was flouting an antitrust settlement by continuing to make it difficult for consumers to use non-Microsoft applications, the sources said. Microsoft spokesman Jim Desler confirmed one change, saying the company will put a function allowing Explorer to be disabled in a more prominent place in its Windows XP operating system. The company also agreed to put in the Windows Help function a tutorial explaining how to switch to other browsers, the sources said.

A U.S. appeals judge questioned a court order that forced Microsoft to put rival Sun Microsystems' Java programming language into Microsoft's Windows operating system. In December, a U.S. district judge ordered Microsoft to place Java into Windows, which is used by 95 percent of the world's personal computers. U.S. Circuit Judge Paul Niemeyer agreed with Microsoft's argument that the injunction was unprecedented in an antitrust case because it ordered Microsoft to do something before a full trial.

RECALLS

DaimlerChrysler recalled about 211,000 Mercedes M Class sport-utility vehicles, model years 1998 through 2003, to replace a hose clamp and prevent leaks in the power-steering system.

Dealers will install smaller clamps on the recalled vehicles, the company said.

Uruguay plans next week to ask holders of as much as $6.5 billion in bonds to accept new securities worth less than what they own, which credit-rating companies said would constitute a default. The government wants to exchange bonds with a maturity of a year or more for securities that would come due on average five years later and pay equal or lower interest. Uruguay is trying to avoid an economic collapse like the one that occurred in Argentina when the government in late 2001 stopped all payments on $95 billion of bonds.
