writes with this selection from PC Pro magazine: "Microsoft's failure to include the EU browser ballot in Windows 7 SP1 cost Mozilla as many as 9 million Firefox downloads, the organisation's head of business affairs revealed. Harvey Anderson said daily downloads of Firefox fell by 63% to a low of 20,000 before the ballot was reinstated, and after the fix, downloads jumped by 150% to 50,000 a day. Over the 18 months the ballot was missing, that adds up to six to nine million downloads — although it's tough to tell if the difference has more to do with Chrome's success or the lack of advertising on Windows systems. The EU is currently investigating the 'glitch,' and Microsoft faces a massive fine for failing to include the screen, which offers download details for different browsers to European Windows users, as part of measures ordered by the EU to balance IE's dominance."
