Solution for the #918899 issue with Microsoft CRM
As you could read on http://blog.sonomapartners.com/2006/08/temporary_solut.html and several other blogs an update for IE (#918899) caused that Microsoft CRM would crash. The technical story behind is when visiting a Web page that uses a custom pop-up object, Microsoft Internet Explorer 6 can close unexpectedly and generate an error in the Mshtml.dll file. The current workaround was to uninstall the update that caused the error. The IE team has released a public download for this issue.

It will also be included in the security update scheduled to release in October.
