Michael: Yeap as you said 3.0 files might work better, however it was one of the first things i tested and it made no difference. It works just as well as 4.0 files do :) but thanks for the suggestion. Now i shall email the model to you, been a bit busy here this morning but now i finally got time so check your inbox in approx 30 min. :) many thanks in advance.

JTB: Hiya and yeap that's me, Maximus from the Maxwell forum :) nice to see you too here.
