Dear Users - yes , I had shared my frustrations with Paul, mostly caused I must say because COOT now worries (excessively I think) about atom clashes and wouldn't let me drag an ARG or HIS or GLU into the obvious density till I had deleted any rogue waters..
However there are real gains - Tandem Refine is great, the new menus are great , etc etc.. And as Paul says - learning new tricks is always a hassle, but worth it I guess (sigh..) Thanks Paul - remember LBC - life before COOT?? Eleanor I think the situation has arisen because Coot users are bringing previous experience of using RSR into their use of 0.9. Because the movement of the non-dragged atoms in 0.8.x was rather unsophisticated, many people learnt (I discovered, rather late in the day) to "flick" the dragged atom with a large and fast movement to get over a local energy barrier.
