Microsoft released a patch (MS07-017) to address a vulnerability caused by the Animated Cursor flaw. However, some users experienced errors after installing the patch, where Windows give a “Illegal System DLL Relocation” error when the computer starts or when the users attempted to run certain third party application. This is due to a conflict of address between User32.dll and Hhctrl.ocx. As such, a new patch is released to remedy this problem. It is available at http://support.microsoft.com/kb/935448.
