Microsoft's security update from Aug. 8 to Internet Explorer is causing browser trouble for some systems.

After people apply the MS06-042 update, rated "critical" by Microsoft, IE may crash when certain Web sites are viewed, the company said in a notice on its customer support Web site. The problem affects IE 6 with Service Pack 1 on Windows XP and Windows 2000 systems, it said.

"Microsoft has identified an issue with the security update MS06-042," the company said in a statement Tuesday. It plans to re-release the bulletin and patch on Aug. 22 for all affected users.

The problem occurs when IE users view Web sites that use version 1.1 of HTTP alongside compression, according to Microsoft's notice. HTTP, or hypertext transfer protocol, is the standard protocol used to browse Web sites.
