Latest Version?
This issue is with IIS6 which shipped with Windows Server 2003, since then we've had IIS7 (Windows Server 2008) & IIS 7.5 (Windows Server 2008 R2) neither of which seem to be affected by this issue.
As IIS6 is nearly 7 years old and has had 2 subsequent releases I don't think you can call it the "latest version"! I would however guess it's the most deployed version of IIS.
