I tried various ideas but they didnt work, Sean told be to use Pythagoras but i didn't quite understand how that would work, i hope you can come up with an idea!

Pythagoras? lol, this is for geometry

Excuse me, You use Pythagoras theorem to get the best results. You calcuate there currect X,Y against there last X,Y and then sqrt it. What i also told Nock44 on msn, Although he didnt seem to listen.

Yes, Sean is right. I actually explained how to do this and posted C# code for it in the other thread on this subject.
