Bill Gates may soon face questions beyond those about his new bestselling book. Justice Department attorneys are reportedly expanding their antitrust probe of Microsoft and have issued several new civil subpoenas to Microsoft competitors, including Compuserve, Netscape and Netcom, to investigate whether the software giant intentionally set up bugs in its new Windows 95 operating system to disable rival internet access programs. Since the August release of Windows 95, numerous companies have complained that Microsoft's accompanying browser, called "Plus!", conflicts and in some cases disables competing browsers when users access the internet through Windows. Don't blame us, Microsoft retorts: their software glitches are the true culprits. The company points out it even has helped its rivals to fix any problems seemingly caused by its software.
