I am getting a HidFind.exe error when logging into windows - this has started since installing recent versions of the Promethean ActivDriver (4.9 or 4.10) onto some of our Dell laptops.

Is this a Microsoft fault or an ActivDriver fault? I am going to uninstall from my laptop, but obviously I need to leave the drivers on for the teachers! It has happened on maybe three out of fifteen Dell D520 laptops so far.

Windows XP Prof SP2 with roaming profiles.

If anyone has seen this before, I'd appreciate a fix!
