Some users were clearly unsympathetic, and blasted the complainers for running an ancient browser. "If you use IE6, you deserve as much pain and suffering as humanly possible," said someone labeled "positrongoo."

IE6 debuted in August 2001, about two months before Microsoft launched Windows XP. According to U.S-based metrics vendor Net Applications, IE6 accounted for 16.9% of all browsers used last month. Rival StatCounter, however, pegged IE6's share over the last 30 days at a slightly-higher 21.6%.

Microsoft may have agreed with positrongoo. Yesterday, when it first acknowledged that Bing had hijacked the search preferences of IE6, it urged users to ditch the old browser. "We apologize for any inconvenience [this] has caused," Microsoft said in a statement Tuesday. "In the meantime, we encourage customers to upgrade to IE8."

Today, Microsoft again implicitly pushed people to upgrade. "This issue did not impact IE7 and IE8 users," the company spokeswoman said.

A Google employee confirmed that Microsoft had, in fact, fixed the Bing bug. "We've been monitoring [this] very closely and are pleased that Microsoft is now reporting that the problem should be fixed," said "Jaime" early Wednesday on the two Google help forums. "If anyone is still having this problem, I'd very much appreciate your posting here to let me know."
