As the Microsoft Corp anti-trust case continues in Washington, the US Department of Justice plans to call software consultant Glenn Weardock, president of Independent Software Inc, Golden, Colorado today (Monday) who will argue that Internet Explorer and Microsoft Windows are viewed by most people as separate products. In a written deposition issued by the court Friday, Weardock contradicts MicrosoftÆs position that the two products are closely tied together and must be viewed as one, and says that users would be better off if the two remained separate. Explorer remains an application and Windows an operating system, Weardock said in the testimony, regardless of how Microsoft groups files together. He pointed out that code for both products has been placed in the same library files, making it hard to remove Explorer without damaging the operating system.
