Dear All, I encountered a problem when trying to rotate or translate a molecule with a grasp electrostatic map loaded. I have three identical molecules, one of which has its surfaced coloured according to the electrostatics from a grasp map. When I use the mouse to rotate all molecules, the grasp map moves along accordingly, but when I rotate an individual molecule it rotates within the map and the surface colours change obviously. So how can I lock the map to a molecule in such a way that I can use the rotate or translate command on a molecule and the map moves with it? Thanks, Peter
