One thing I defintly don't like about the Fritz-winboard interface is how much control the fritz interface takes, ie making it resign, take draws, and of course the, well, what is really quite a poor way of handling the interfaces as you said. In fact while writing this, Doctor?3 vs TCB 045, when TCB pondered correctly, it appeared that Fritz didn't update the move or something. As TCB was able to just continue on at 9 ply or so, rather then start over. Jason
