Microsoft will update a patch by next Tuesday that's causing a version of IE (Internet Explorer) to suddenly crash.

The patch, MS06-042, fixed several security vulnerabilities, Microsoft said yesterday. A 'hotfix' is available pending the forthcoming update.

The trouble affects users running IE 6.0 with Service Pack 1.0 on the Windows XP OS (operating system) running Service Pack 1 or the Windows 2000 OS with Service Pack 4.

The problem occurs when visiting a website that uses a web coding standard, HTTP 1.1 (hypertext transfer protocol), and compression, Microsoft said.

The fixed patch will be available through Microsoft's Download Centre and through Windows Update, an OS feature that checks for updated software.

Microsoft released 12 security fixes on 8 August for its OS and Office software, nine of which were labeled 'critical'.
