logon compatibility issue

Yes, it does. There is a Microsoft bug for one of the platforms that runs Clarizen that is preventing login with IE11. Microsoft has already issued a patch, but in order to apply it we need to restart the servers. We can only apply the patch during our next maintenance window, but rest assured that a resolution is coming soon.

Good news, we have a workaround available for IE11.  All you need to do is add Clarizen to compatibility mode as you can see in this video:  http://screencast.com/t/fLkEFpqEOo
