No, not to my knowledge. I did have Pareto Logic recommended to me - but having asked my fellow Forum members about it, I was wel warned off! So I did not touch it! Funny, though, that this name should be appearing in the dialogue box!!
The site you have suggested, gave me an example of exactly the same problem! By following the advice there, Start\Accesories\Schedule tasks I was able to find two items of Pareto Logic origin. I've deleted these and am now keeping my fingers crossed! Dear knows where the the PL items came from! Thanks folks for your help!!
