the funny thing is that each and every year we discuss this topic, but the emdl has been on the server since 2003...

Helge! you just saved my a$$
I was pretty much starting to get really stressed with this project :) when we accepted it, I thought a few animated constraints will do the trick, I will not bore you with all the details, but failing with this project, would probably cause me to loose my job...
If I was a princess, you would be my hero :)
thank you so much!
Oz.
