CPU/Wall Clock did not make any difference, but "Top-down (any method) did!. The Display defaults to Top-down (methods with source). Our solution does not contain the actual .net source although I am able to trace into it the source from the devstudio debugger.
So, I suppose the next questions is: is there a way to tell Ants where to look for the .net c# source?
Thanks for the prompt reply, you got me going!
