errors during restart after switching on lockdown

Trying out lockdown for a customer. When restarting or logging on again after switching on lockdown, always 2 error windows appear named: "DisableTaskbarOnTop - Error" Message: unknown explorer version (6.1.7601.17567), can't apply patch.
This error appears twice. In between the splashscreen of lockdown appears.
The errors have to be clicked OK, to get rid of them.
I tried to uncheck all options in lockdown (V2 - multiapplication edition), made no difference. Using W7 home premium SP1 64bit dutch version.

Please comment.
