Just after releasing the Internet Explorer 8 at the MIX09 conference in Las Vegas on Thursday, Microsoft via email messages thanked the testers for their hard work & support and asked them to continue testing the new web browser for flaws that were previously marked as fixed and keep posting their feedbacks and keep reporting the company about the new bugs, if they find any.

Microsoft said, "We are looking for new IE8 bugs and bugs that have regressed (meaning the bug was previously fixed and now occurs in IE8 RTW)… The Internet Explorer 8 Feedback website on Microsoft Connect will remain open and we will not delete any of your previously submitted bugs. In the next couple of months, we will introduce a new type of feedback form designed specifically to handle improvements for the next version of Internet Explorer."

Meanwhile, Microsoft has been getting mixed response on its Internet Explorer 8. Some users have posted negative feedbacks, while some have sent positive feedbacks.

Some of the early users of Internet Explorer 8 have reported that the new browser causing some unexpected problems, such as missing Web content, system crashes, and Internet tools that don't function properly

On the Microsoft's Internet Explorer 8 Feedback page, one of the early users, who identified himself as Aviramoff wrote, "I have just installed IE8 and still the search option doesn't work. All I get is a blank line with no search box so what and where is the problem?"

Bob, another user, complained that IE8 was not displaying some sites properly. Bob wrote, "After downloading IE8 I cannot print any card from American Greetings. The message I get is, 'An error occurred during the operation."

Phil Wheeler, another user, reported that IE8 didn't show even the pages created with Microsoft's own Web publishing software, properly. Wheeler wrote, "I created my company's Web site using the MS Publisher 2007 template. After upgrading IE7 to IE8 my menu tabs and many important images no longer show."

However, some of the users, like Lambert, sound pretty happy and contented with IE8. Lambert wrote, "In my first 30 minutes of using IE8 on my Vista Business Edition I am very pleased. The browser opens in a quarter of the time that it did in IE7. Normally I would not bother posting such an effusive comment, but IE8 is that good."
