"We are aware of the issue with Bing on machines running IE6 and are investigating a solution," Microsoft said in a statement. "This issue is not impacting IE7 and IE8 users."
Although it is only affecting its older browser, many people still use IE6 and Microsoft has faced a lot of regulatory scrutiny over how default search preferences are set and changed within Internet Explorer. A recent Forrester Research study showed that 60 percent of businesses are still using IE6.
The issue crops up just as Microsoft plans to formally launch Bing. Among its planned promotions is a huge ad campaign as well as an event Tuesday night at Seattle's Space Needle.
The IE6 issue was noted earlier on Tuesday by Search Engine Land.
